I don't think anyone on this thread has said the British should win. I'm just surprised at the earlier suggestion that the BAFTAs are notoriously 'pro-British'. I don't think the BAFTAs are about favouring a particular country at all.
However, the idea that the winner 'rises' above the others in the category by being the 'best' is rather simplistic and a bit daft, don't you think? The Best Film category, for example, draws together films of differing style and substance, with various messages, plots, themes and tensions. Determining the winner is a purely subjective thing in the end. It is certainly not, as far as it was explained last night, about trying to isolate the 'most deserving' from the pile of also-rans. Frankly, I don't think any one of those film choices was better than the others.
Clearly, tastes differ as to who the winners 'deserved' to be. You obviously think Wallace and Gromit was less deserving of an award than other films in the British Film category, and you're entitled to your opinion. But I think to describe a film of this calibre and class as 'stupid' is betraying a rather snotty attitude to film-making, British or otherwise. It might not be to your taste, but there is nothing 'stupid' about a film that exemplified so much talent, effort and total joy in the craft.
