C+Q - Let's Kill Hitler (2011)

Let's Kill Hitler is one of my favourite Series 6 episodes. It's a fun, energetic rollercoaster; the perfect opener for a new run and a great way to inject life into the midpoint of a complete series. It is a bit of a weird one though, and I don't mean 'weird' as in 'whimsical'. Usually the Doctor and the companions show up in the middle of someone else's adventure and fix everything, but here the plot revolves around the show's main characters and recent mythology. It's strange for an episode of Doctor Who to be so about Doctor Who.

It's called 'Let's Kill Hitler' but it's not about Hitler at all. An interesting story might be possible using the Doctor vs. Hitler but it's not as if the Doctor could change history that drastically. The episode introduces Hitler, punches him in the face, and locks him in a cupboard, which is about as much as I'd expect a time travel family show could realistically do with him. With that checked off the list, the real adventure begins with River on the loose in wartime Berlin. Alex Kingston is brilliant as always but it's especially fun to see her playing a post-regeneration River. That period of instability after a regeneration is really just an in-universe way to excuse a new actor of any weirdness while they're still figuring out how to play their new role, so it's very bizarre and entertaining to see that retroactively applied to an actor who's already so comfortable. It's also a lot of fun to see a new incarnation of River, played by Nina Toussaint-White. I'm sure Big Finish will eventually call her up for a series.

Unfortunately, no-matter how hard this episodes tries, the 'River Song being Mels' thing will never hit that hard because we've never heard of Mels before. At the very least a line of dialogue in The Impossible Astronaut or Day of the Moon (considering they were also written by Moffat) could've smoothed this retcon out a bit. There's nothing wrong with retcons - after all, the Doctor being a Time Lord from Gallifrey is a retcon. Thing is though, if Rose can make an off-hand comment about her mate Shareen and Martha can quote her friend Vicky, there's no reason why Amy or Rory can't mention their best friend Mels. Of all the heavy arc stuff Let's Kill Hitler does, the Mels retcon is the weakest. It still works because this is an entertaining farce of an episode that handles the reveal well, but it's a little awkward. Other than that, River's continuity stuff is really satisfying, like the explanation of how she can fly the TARDIS, and the Doctor giving her the blank diary at the end.

The Teselecta stuff is great too, and introducing it after the main mystery of Series 6 has already been set in motion means I didn't see the big twist with it in the finale coming. It makes perfect sense though, and just the basic idea of a shapeshifting robot piloted by miniaturised people is so wonderfully Doctor Who. The Teselecta gives us the first reference to The Question, and that stuff all holds up too given what we learn in The Time of the Doctor. See, all these pieces fitting into place and being well set-up in advance of their pay-off is what makes the Mels thing stand out.

Let's Kill Hitler is the sort of episode I'm always in the mood to watch. It's got some really strong gags, like River telling the Nazis where she's going and Rory's impression of Amy's accent, and it progresses the plot significantly, with the Doctor finding out about Lake Silencio. It is kinda unexpected that the search for River happened off screen between Part 1 and Part 2 of the series, but it also keeps the story moving along nicely.

Also, the Doctor's new coat is cool.
