It is quite something when a series with so many known parameters and constituent elements can still be juggled together and delivered in a fresh manner. And yet Steven Moffat once again manages to do just that in Let's Kill Hitler!
For instance, regeneration. Back in The Christmas Invasion we learn that Time Lords are in a state of flux during the first fifteen hours where-in their bodies can 'regenerate' any damage. Then, in Journey's End the Doctor reveals that residual regenerative energy can be siphoned off into an appropriate vessel. For Let's Kill Hitler, Moffat skillfully revisits those ideas in the form of River, at one point reveling in her ability to shake off a hail of bullets, and then ultimately channeling her own energy into the Doctor to save him.
Then, for River herself, the signposts were pretty easy to read that the little girl from Day of the Moon was going to be her, cemented in A Good Man Goes To War with her being conceived in the time vortex within the TARDIS; but then not only does Moffat play a neat trick by having us first think it is River in the red corvette at the start only to see Mels instead, reveal her as a childhood friend of Amy and Rory, only then to further reveal it really was River after all! (why didn't I pick up on the name "Mels" straight away?!!!). Not only that, Moffat also gently guides us into preparation for the possibility of a black Doctor!
The stuff with Hitler was amusing, especially as the eponymous character is actually only a comedy sideline - though he did of course play a pivotal role in "killing" Mels, which is quite ironic considering it was her suggestion to go kill him! And of course nobody knew the Teseracta crew were also there for similar reasons!
But that's a minor niggle in amongst the gems, especially in the acting. The interplay between Matt Smith as the Doctor, and Nina Toussaint-White/Alex Kingston as Melody was great fun, and I should also mention Caitlin Blackwood being as enchanting as ever as both the young, innocent Amelia and the TARDIS's voice interface - "fish fingers and custard" was worthy of a great cheer!
I must admit I didn't find sub-plot of the crew on the Teselecta as interesting as what was revolving 'outside'. The antibodies almost felt like a contrived "alien of the week" was needed to menace our regulars, and the crew's mission to punish those who have committed heinous crimes might have been laudable except that it was (a) torture, and (b) they didn't seem to care that much about others they happened to steal identities off to reach their goal either. Still, I don't think we've seen the last of them ...
On the other hand River goes from strength to strength. The wibbly wobbly timey wimey way in which we've encountered her has been one of the most fun elements of recent series, and now we have her arising phoenix-like into the Doctor's life for the first time (her perception). And full credit to the consummate ability of Alex Kingston to bring River 'to life' as someone totally ignorant of who she will become to the Doctor (and us) yet the little quirks of her personality we know and love literally evolving as the episode progresses. There are still some big gaps in her life though, but these quite possibly will feature in future storylines! And I'm looking forward to them!
Back to intriguing ideas, as well as the question of Time Lord's "ethnicity" neatly answered this episode, there's also the moment when River ploughs all her remaining lives into the Doctor - have we just seen Moffat's masterplan for the Doctor to continue on beyond his thirteenth incarnation subtly put into motion ... (or did she really use up 504 lives if you accept the Death of the Doctor comment of course!)
I'll leave you with an even more subtle idea, which maybe even Moffat hasn't considered (not that I believe that for one moment, nothing he writes is throwaway!); this series has effectively revealed with River that it is possible to 'reboot' the Time Lords (well, Time Lord-like beings) as a more innocent race to once again inhabit the universe ...
However, whilst the plot itself might be shaky, character-wise the episode performed well with an interesting exploration of Jack's view of the ephemeral nature of his relationships with us mortals; as mentioned above, though, it isn't clear if this is pre- or post- Ianto Jack - if he had only been on Earth for some 40 years so far would he have had that many relationships? Still, as other reviewers have observed, this series does seem to be concentrating on Jack's male exploits (and possibly some slash-fiction asperations on the part of the writer who handled both these encounters this series?!!). Not that this matters to the story per se, but it does feel neglectful of the character's inception as an omnisexual 51st Century guy (something that River seems to have taken up the reigns of in Doctor Who, judging by her anecdotes!).
The Middle Men would seem to be an apt name for this episode, which falls in the middle of the run so far; however it could also be used to describe what can only be termed a middling episode, too - if we've seen episodes that seem to tread water, this one comes across as simply giving up and putting its feet on the shallow bottom for a rest.
Okay so what did happen? We had Maloney trying to cover up the effective murder of Vera and then torturing Rex. I assume we're watching someone who is rapidly losing the plot (in which case I totally sympathise!). We had Gwen shouting her mouth off at a doctor in such a way that I fully expected her to get arrested rather than allowed to roam the camp as she pleases, even though last week she'd pretty much blown her cover. Jack had about the only bit of plot movement in his meeting with Owens - yay for Ernie Hudson - but only insomuch as it shows episode four was a wasted runaround. (Actually I got distracted more by remembering that this was filmed when John Barrowman had his birthday!). Speaking of Owens, the whole 45 Club thing just seemed to be a set-up for a pre-titles "joke" - sheesh!
I must admit I was genuinely shocked by Vera's demise. In previous posts I've said I was ambivalent to her character, but I guess I found I was rooting for her as her fate became clearer. But then this is Torchwood, people die (young), and her death is in keeping with the "grittier" stance of this spin-off. But she was a redundant character anyway, so in some ways it was just a way of not having to juggle the character with the others.
Or was there. Actually thinking back on what I just watched, there was Esther/sister plot, the tracking of Torchwood in L.A., the hospital opening and Oswald's ascension, the Ellis Hartley Monroe campaign, and the Torchwood infiltration of Phicorp. And plenty of waffle as usual. But I guess the fact that the team actually saw some action this week, going on their mission and having an "enemy" to fight gave it more oomph than in previous weeks.
John Barrowman and Eve Myles continue to carry the show, though there still seems to be a missing spark in their characters that used to ignite previous series. Can't quite place what it is, but it might be the lack of "action" that they undertake themselves. Thinking about it, all we've really had is a chase across a beach, and then Gwen decking Lyn, but that's about it so far. The old Torchwood team certainly didn't rally through when "The Gentleman" (good old Christopher Thomas Howell as the other "guest of the week"!) knocked them about in the server room, but then that might have been a plot manipulation to make new boy Rex seem more integral to the team. [as an aside I have never seen a server room that clean, and spot the wobbly server!!!]
