Most impressively, Doctor Who season 11 has maintained a consistent level of quality over its 10-episode run. Indeed, none of the episodes are particularly weak; something that's actually quite rare for an entire season of Doctor Who. Unfortunately, it also doesn't have many instant classics either. This was a serviceable first season for Chibnall and Whittaker, and it was definitely effective, but not many episodes are likely to be talked about in the same sentence as "Blink" or "Heaven Sent". Meanwhile, the lack of compelling villains has damaged the effectiveness of several stories; most of the villains in Doctor Who season 11 are intended as mirrors on an aspect of human nature, an approach that works well but would have been better used intermittently.

Now the show is over for 2018 (with only a New Year's Day special in 2019), it's the perfect time to cast our eyes back over every episode and rank them from worst to best. What worked, and what didn't, in Doctor Who season 11? Let's talk a run through Jodie Whittaker's first season.

10. The Tsuranga Conundrum

One of the weaker episodes of Doctor Who season 11, "The Tsuranga Conundrum" drew on classic sci-fi tropes - but not in an entirely convincing way. In thematic , this is essentially a "base-under-siege" episode, with the Doctor and her friends attempting to ensure a monstrous creature known as the Pting doesn't destroy their spaceship. Unfortunately, all sense of drama is lost when the Pting finally appears on the screen, it's frankly not particularly threatening.

9. The Witchfinders

A traditional historical adventure, "The Witchfinders" opens with the Doctor intervening in a witch trial, and things just go from bad to worse for the Time Lord from there. Soon she's discovered an ancient alien threat lurking beneath Pendle Hill in Lancashire, attempting to escape its prison and conquer the planet. Alan Cumming is a classic guest-star as King James, even if the monarch's presence at Pendle Hill is absolutely inexplicable in plot ; it's simply impossible to imagine a scenario in which the King would be wandering across the country, with only a single guard at his side. What's more, his disguise - a metal mask - is more likely to draw attention than to avoid it. This particular plot twist takes suspension of disbelief beyond the breaking point for even Doctor Who.

8. The Ghost Monument

The second episode of Doctor Who season 11 was really all about the TARDIS; the Doctor's quest to recover her beloved vessel left her and her friends stranded on the doomed world of Desolation. There, they wound up caught in a deadly game of survival, where the contestants battled against the nightmarish environment in the hope of acquiring incredible wealth. The episode was seriously atmospheric, with the real villain being selfishness and greed; victory came from the Doctor encouraging everyone to work together. Unfortunately, "The Ghost Monument" is a somewhat flawed episode. No explanation is ever provided as to why the Doctor's regeneration was so destructive this time, nor why the TARDIS wound up out of phase on Desolation for millennia. A tease of the "Timeless Child", expected to tie into a season-wide arc, was also left unanswered.

7. Demons of the Punjab

A strong character-focused historical adventure, "Demons of the Punjab" felt a little too similar - both structurally and thematically - to an earlier season 11 episode, "Rosa." As is common in the new Doctor Who, it introduced a brand new alien race of apparent villains, only to turn the plot upside-down; it turned out the Thijarians had long since given up their warlike ways, and were instead traveling through time and space bearing witness to the deaths of those whose deaths history barely even noticed. It was good to have an episode focused in upon Yaz, even if it wasn't the strongest.

6. The Battle of Ranskoor Av Kolos

"The Battle of Ranskoor Av Kolos" feels more like a standard episode than a big Doctor Who season finale. The Stenza were introduced back in "The Woman Who Fell To Earth" and were referenced as background threats in "The Ghost Monument." Season 11 had forgotten them since those first two episodes, however, and as a result their return was anticlimatic. Tzim-Sha - or "Tim Shaw," as the Doctor insisted on calling him - has turned into a full-on megalomaniac in the 3,000+ years since he crossed paths with the Doctor and her friends. He's now attempting to avenge the Stenza be destroying all worlds that ever dared to frustrate or oppose them. In theory, this episode should be a lot stronger than it is; it certainly has the right stakes, with Tim Shaw even attempting to destroy the planet Earth. But the pieces don't quite come together well enough. "The Battle of Ranskoor Av Kolos" probably had the potential to be a classic, but it's not realized.

5. It Takes You Away

Easily the weirdest episode of Doctor Who season 11, "It Takes You Away" is a powerful exploration of grief and loneliness. The plot has massive problems, with a lot of twists that seem to have happened purely for story purposes whether or not they actually make any sense. But the episode is largely redeemed by the sterling performance of the cast, most notably Bradley Walsh as Graham, who's still grieving the death of his wife. The central concept - the idea of the Solitract, a cosmic force whose very presence in our reality would cause the physical laws of the universe to collapse - is an interesting one, even if it is handled in very strange style. When the Solitract manifests itself in the form of a talking frog, the Doctor speaks for all viewers; "There's me thinking the day had no more surprises left," she observes.

4. Arachnids in the U.K.

"Arachnids in the U.K." exploited a classic Doctor Who trope, with the monster of the week adding a touch of horror to an aspect of everyday life. Sheffield was being ravaged by giant spiders, and - in a twist vaguely reminiscent of classic Who story "The Green Death" - the Doctor soon discovered that human greed was really responsible for it all. The villain of the episode, Presidential hopeful Jack Robertson, was clearly intended as a critique of Donald Trump - and, frankly, that was done in far too unsubtle a style. While this was another "one-and-done" episode, it was still one of the most important hours in season 11's narrative arc; the return to Sheffield gave the Doctor's friends an opportunity to decide whether or not they wanted to be part of "Team TARDIS" in the first place.

3. Kerblam!

Another episode in the vein of classic Doctor Who, "Kerblam!" felt very much like a homage to the John Nathan-Turner era. Like "Arachnids in the U.K.," it exploited the traditional idea of turning an aspect of everyday life into a deadly threat - in this case, the danger is Amazon writ on a galactic level, and the villain's weapon of choice is literally explosive bubble wrap. It was a strong episode, and the bubble wrap served as an entertainingly meta-commentary on the budgetary problems Doctor Who has often struggled with. Ironically, though, it was damaged by poor-quality CGI - the modern equivalent of those old-school budgetary issues.

2. The Woman Who Fell To Earth

The first episode of Doctor Who season 11, "The Woman Who Fell To Earth" had the power to make or break this entire series. There's always massive pressure on the debut episode of any Doctor, but that was especially the case for Jodie Whittaker, the first female actress to play the part. Fortunately, Chris Chibnall's script took the smart approach of barely acknowledging the sex change at all. "Sorry, half an hour ago I was a white-haired Scotsman," the Doctor observed, and then the story simply moved on. It was the perfect way of handling the regeneration, especially as, by the end of the episode, Whittaker had proved herself every inch the Doctor.

The premiere set the tone of the entire season. It was as much about the Doctor's friends as about the Time Lord herself; that's why so much of the opening sequence is spent exploring the lives of Ryan, Yaz, and Graham. The title has a beautiful double-meaning to it too; it doesn't just reference the Doctor's arrival on Earth but points to the death of Grace, which is really the inciting incident of this entire season. All in all, "The Woman Who Fell To Earth" is a strong episode. It's not perfect - Tim Shaw and the Stenza don't feel like too much of a threat, and the final confrontation doesn't quite work on second viewing - but it was a strong start to Doctor Who season 11 all the same.

1. Rosa

Undoubtedly the strongest episode of Doctor Who season 11, "Rosa" dared to rewrite the tired formula of the show's historical adventure. This time around, the historical nature wasn't just the context for yet another alien invasion; it was the very heartbeat of the story, as Team TARDIS realized that the past truly is a foreign country. The episode's villain, the time-traveling white nationalist Krasko, seems pretty weak at first glance but in actuality is a symbol of a far greater threat. In "Rosa," the real enemy is racism; the monsters are the people of the Deep South, ranging from policemen to waitresses, and of course to the bus driver himself. Ryan and Yaz's musings serve as a reminder that the battle against racism is ongoing, while the very presence of Krasko points to the fact that prejudice will sadly always be a part of human nature - and much always be fought. Although not perfect, "Rosa" is probably the one classic episode in Doctor Who season 11, and will be fondly ed for years to come.
