As with yesterday’s post, I’m trying to derive some meaning from the Internet Movie Database’s user ratings of Doctor Who episodes. Here, for your edification and delight, are the top-rated episodes from each of the incarnations of the show. (Based on these statistics.)
The twentieth episode of the Australian K9 spinoff series, 2010’s Taphony and the Time Loop, has a better rating, at 5.7, than any of the other twenty-five K9 episodes, but that is still lower than any episodes of the Third, Fourth, Fifth, Eighth, Ninth, Tenth, Eleventh, and Twelfth Doctors, or of any of the other spinoffs. I agree that it’s probably the best of the undistinguished run of the Aussie show, with an escaped Time Being in the shape of a cute girl (Taphony, played by Maia Mitchell) draining the essence of the regular cute girl character (Jorjie, played by Philippa Coulthard) and K-9 sorting it all out. It’s still not particularly good, though; I rewatched it last week for this post and I think it deserves a little better than 5.7. Maybe 5.8.

The metal mutt takes both of the bottom places in this list, in fact, with A Girl’s Best Friend, the only episode ever made of the unsuccessful 1981 spinoff K-9 and Company, scoring a lowly 6.1 with IMDB users. This brought back both Lis Sladen as Sarah Jane Smith and John Leeson as the voice of K9, but had a very silly plot involving pagan cultists in the English countryside – not natural Who territory, and a story that has been told much better before and since by others. Sarah Jane, of course, also went on to have her own much more successful spinoff.

The second and final episode of 1985’s Revelation of the Daleks is the top-rated Sixth Doctor story at 7.7 (and the first episode of the story is in second place at 7.6). I agree that this is the one story where the Six/Peri pairing comes together, partly because they’re not actually in the story all that much. If you can overlook the huge plot flaw of Davros feeding the entire galaxy with the corpses of a few rich people, it’s very well done, with various different factions of characters motivated for different reasons.

Village of the Angels, the fourth of the six-part Flux storyline, is the top-rated Thirteenth Doctor episode. I am among the many who found this series difficult to follow, but this was a good instalment, with many murky and dramatic goings-on in the Village, culminating with the Doctor herself being transformed into a Weeping Angel. IMDB users rate it at 7.8, which again seems a bit mean.

The top-rated episode of short-lived 2016 spinoff Class is its finale, The Lost, ranked at 8.1 and ending with a massive battle between the Coal Hill Academy kids who have been charged with the defence of Planet Earth and the alien Shadowkin. Alliances and friendships are forged and broken and several significant characters are (apparently) killed off. We are left with a massive cliff-hanger regarding the new nature of regular girl April, which presumably would have been resolved had the BBC commissioned a second series. It’s a shame that they didn’t. I couldn’t recommend watching this on its own, but there are only eight episodes altogether, so you might as well watch them all. I was myself rather disappointed by this episode; my own favourite of the eight is the third, Night Visiting.

The top-rated surviving First Doctor episode, broadcast the day after Christmas Day in 1964, saw the first ever departure of one of the regular characters in Flashpoint, rated 8.3 by IMDB users, the last of the six-part story that we now call The Dalek Invasion of Earth. Susan, the Doctor’s granddaughter, falls in love with a Scottish resistance fighter against the Daleks who bears an uncanny resemblance to David Tennant (six years before David Tennant was born), and is left behind on Earth to build a new life, Hartnell delivering one of his great set-piece speeches in farewell. Actually my own favourite episode of this story is the third, Day of Reckoning, which features a desperate scramble across a deserted London. But I won’t fight (much) with those who prefer this one.

The top-rated Seventh Doctor episode is the second of the opener to his second season, Remembrance of the Daleks, at 8.5. It took me a while to warm to this story, but I have come around to its good points. I still prefer the middle two stories from the final season of Old Who, Ghost Light and The Curse of Fenric, but there are a couple of great set-pieces in this episode, with the Doctor retrieving the Hand of Omega from a London gravesite in 1963, and Ace menaced by Daleks.

The top-rated Third Doctor episode, also at 8.5, is the second last of his 1970 debut season, the sixth of the seven parts of Inferno. The story concerns a dangerous experiment to drill into the Earth’s crust; for several of the episodes, the Doctor is transported to a parallel Earth where his friends are all fascists and the experiment is further advanced. In the sixth episode, despite the Doctor’s efforts, the parallel Earth begins to disintegrate and he escapes back to our timeline. It’s dramatic doomed stuff, and I think I’m with the IMDB voters here.

I’m surprised to see a lost episode outpolling all of the surviving First Doctor episodes, but it’s a good one. My favourite Hartnell story is the thirteen-part epic that we now (mostly) call The Daleks’ Master Plan. Only three episodes survive, and they do not include the finale, Destruction of Time, in which the Doctor activates the Time Destructor in order to defeat the Daleks by aging them into oblivion, but loses his own companion Sarah Kingdom in the process. IMDB voters rank it at 8.5, which I think I can agree with. You’ll appreciate it more after experiencing the previous twelve parts of the story.
I think that the best single story of the Sarah Jane Adventures is Whatever Happened to Sarah Jane Smith? from the 2007 first series, in which she is replaced in her life history by the ambiguous Andrea, played by Jane Asher. IMDB users rate its two episodes third and fourth at 8.6, but rank two other episodes with visiting guest stars from the parent show just a bit higher at 8.7: in second place, the second part of 2010’s Death of the Doctor, with Matt Smith (and Katy Manning), and at the top, the second part of The Wedding of Sarah Jane Smith, for which David Tennant did his last filming in his first run as the show’s regular star in 2009. Sarah has been yanked into a prison dimension through a fake wedding with a rotter played by Nigel Havers and the Doctor turns up to save her with her friends. Great stuff.

There’s a fairly strong fan consensus that the Fifth Doctor’s final story, The Caves of Androzani, is also his best, and IMDB voters also subscribe to that view; its four episodes hold four of the top five Fifth Doctor spots in the system (the other going to the last episode of Earthshock). And the best of the four, according to IMDB where it is rated 8.8, and also frankly in my own opinion, is the last, where desperate people fight over dwindling resources and lives are brutally and dramatically ended, including the Doctor’s own. Poor Peri doesn’t get much to say except at the end, but it’s her second appearance in this list.

While I’m not surprised that the Eighth Doctor’s unexpected 2013 return in Night of the Doctor rates higher then The Movie, I am surprised that it rates as high as 9.0 on IMDB. It’s less than seven minutes long, and I feel that fannish enthusiasm at the time of the fiftieth anniversary has not yet been tempered by sober reflection.
In general I’ve been concentrating on the top-rated single episodes for each case, but for the Ninth Doctor’s 2005 series, the top two episodes, rated 9.0, are a two-part story, The Empty Child / The Doctor Dances, which also incidentally won the Hugo Award that year. This is the one introducing Captain Jack Harkness, set in WW2 London, famously featuring the gasmask zombie child asking “Are you my mummy?” My own favourite Ninth Doctor story is Dalek, but I’m clearly not with the majority. The second part, The Doctor Dances, is a hair above the first part on IMDB.

My own favourite Second Doctor episode is the completely bonkers opening to The Mind Robber, but IMDB voters disagree. Their top-ranked episode of the black-and-white era is also the very last: the tenth episode of epic 1969 story The War Games, rated 9.1. Having invoked his own people, the Time Lords, to defeat an alien mastermind’s evil plans, the Doctor himself is put on trial for interference in cosmic affairs, and sentenced to exile on Earth, his companions sent home with their memories wiped. The final shots, as he howls in protest at the Time Lords changing his face, are among the bleakest of the whole of Doctor Who (cf above mentions of The Daleks’ Master Plan and Earthshock).

My favourite story of Old Who is the Fourth Doctor’s The Deadly Assassin, from 1976. But I find it difficult to argue with the verdict of IMDB users that the best single episode of Old Who, rated 9.1, is the sixth and final part of 1975’s Genesis of the Daleks, in which their crazed creator Davros loses control of the malevolent pepperpots. (It’s their fifth appearance on this list.) There are many beautiful moments here, including Davros’s large button marked “TOTAL DESTRUCT” which lurks like Chekhov’s gun.

The spinoff shows have had a mixed success rate here, but Children of Earth, the third series of Torchwood (co-starring Peter Capaldi as a harassed senior British government official), is in a league of its own, its five episodes ranked between 8.7 and 9.2, all of them higher than any First, Third, Sixth, Seventh or Thirteenth Doctor stories. The top-ranked episode is the fourth, which features the growing evidence of Jack’s involvement with the alien threat to the world’s children, and famously ends with the demise of the much-loved Ianto, and I think I’d support that choice, though maybe not put it as high as 9.2.

We’re getting near the end here. I totally agree with the final three verdicts by IMDB voters. Their top-ranked Eleventh Doctor story, at 9.3, is Vincent and the Doctor, with its intense portrayal of artistic genius and mental illness, leavened by an alien incursion. I was surprised that the 2010 season closer, The Pandorica Opens / The Big Bang, won the Hugo that year; the verdict of history, I think, is with Vincent.

The top-rated Thirteenth Doctor episode, 2015’s Heaven Sent at 9.6, is again my favourite from the era, with the Doctor, newly bereaved of Clara, trapped in a mysterious castle where he must recapitulate a cycle of death and renewal, over and over. I think it’s tremendous, though very different from the norm.

And finally, my favourite Doctor Who episode of all time, and also well clear at the top of IMDB’s rankings, is the Hugo-winning 2007 Tenth Doctor story Blink, which introduced the Weeping Angels and communicated much of its plot through DVD Easter eggs. I loved it on first broadcast and I still love it now. IMDB voters give it a massive 9.8 out of 10. It also won the Hugo Award. Although it barely has the Doctor and Martha in it, I think you could safely show it to someone who had never seen Doctor Who before, and who wondered if they would like the show; it would be a valid litmus test.

Steven Moffat wrote four of the above (Night of the Doctor, The Empty Child / The Doctor Dances, Heaven Sent and Blink) and Terry Nation is credited with two (Genesis of the Daleks and Flashpoint, though there are varying reports of the real extent of his input). Graeme Harper, David Moloney and Douglas Camfield are each credited with directing two of them (Harper: Revelation of the Daleks and The Caves of Androzani; Moloney: The War Games and Genesis of the Daleks; Camfield: Destruction of Time and Inferno, though in fact he was too ill to direct episode 6 of the latter).
I am a little surprised that the greatest Old Who writer Robert Holmes appears in both the “best” and “worst” lists, for The Caves of Androzani and The Space Pirates respectively. As previously noted, I think The Space Pirates is underrated. Director Andrew Morgan did only two Doctor Who stories, but one of them is on each list, Remembrance of the Daleks here and Time and the Rani yesterday.
