Eurovision's been around since the 1950s. So this won't quite be the same as S1's tribute to flavor of the month reality TV shows.
Isn't it a bit late to be worrying about that sort of thing in Doctor Who? And besides, is it really any different or worse than Star Trek depicting galactic civilization as Space America?
The episode title wouldn't have been made public like this unless that wrangling had already been taken care of.
Oh I’m not saying we shouldn’t do allegory in SF or Who. Or kooky. But (a) when you do allegory you make it subtle (unless you’re a full on parody show, and even then…) you don’t call an episode ‘space nazi’s’. The fan base will do that for you. (I appreciate the joke and why it’s there, for instance, but ‘Let’s Kill Hitler’ is terrible as a title for Who.) I also don’t trust current RTD not to offensively fuck up.
