The Doctor's frantic search for the infant Melody Pond takes him to 1930s Berlin, where he comes face to face with the most notorious war criminal in the universe. With conflict brewing in the background, the Time Lord prepares to teach his enemies a lesson in responsibility. --- Weak. I'm sorry to say that, in my opinion, the wait was not worth it. There was very little to an episode that had some very good ideas - the justice robots could be so much more but, instead, they wind up in what has to be Moffat's worst episode. Ah well, the honeymoon had to end somewhere... The story was simply daft, the joviality in the acting was horribly forced and the twists and turns in the plot were obviously the result of a brainstorm with a class of six year-olds. The only positive to come from it was the development, however shallow it was, of Melody/River's character - I can now update my River Song thread with a much more accurate timeline (and we know, for a fact, that the character finally dies... unless some hyperactive Time Lord comes back and gifts her more regenerations). Oh, and the TARDIS has a horrible sense of humour whilst the Doctor is burdened with almost fatal guilt. Out of ten, I'm going to rate it even worse than TEiN will.
