The Black Swan, The Kings Speech, The Social Network, True Grit, Inception, Winters Bone, Toy Story 3, The Fighter, The Kids Are Alright, 127 Hours.
I've seen the first five on the above list and would be hard placed to pick a winner, though it wouldn't be The Social Network for me (I'm a bit too old to have much interest in the Facebook thing). I'm very much looking forward to seeing 127 Hours as I just loved Slumdog Millionaire and have liked most of Danny Boyle's films to date. Also Winter's Bone has it's appeal to me, but I can't say the others really grab me much. I'll definitely see them all however just in the manner of collecting a set of prints

ps. Can anyone explain how it is that the 'Best Director' need not make the 'Best Film'. I never qiute got that as it seems to me a logical step that the criterea for the judgement of a director has to be the quality of the film he makes. (Or could it be the one that the actors like best. ie Lets them skip off to the pub and stuff when they should be practicing their lines and whatnot. Naaaah......Surely not!)
