Sob, sob, sob. Actually I’m sure it’ll be ok. Russell T. Davies will write an amazing regeneration for Tennant (just like he wrote an amazing regeneration for Eccleston) and Stephen Moffat will pick and create an amazing 11th Doctor. I can appreciate why Tennant decided to leave alongside Davies, he’s leaving whilst the going is still good and he’s an amazing actor and I’m sure we’ll see him in a lot more stuff, even if it does mean I have to go to RSC more often.
As for who will be the next Doctor, I quite like the look of the current favourite Joseph Paterson better known as the Marquis de Sade Carabas (whoops, what does that say about my psyche?) in Neverwhere. There’s something about his eyes and that’s the crucial thing about a good Doctor, those eyes have to look like they’ve been around for 900+ years and that they’ve seen things. Consequently whoever they choose as the next Doctor can not be too young, so definitely not that Russell Tovey that Russell T. Davies likes (not that his opinion will count in the decision). The top of my personal wish list though for the next Doctor definitely has to be Rupert Penry-Jones, well he’s not in Spooks anymore and I think he’d be good and very very cute.
