In my memory, not singing herself and the omission of WWII were equally offensive to Dr. Kermode, and about the only two things I can remember he ever said about the film. And both complains seem very valid to me. I haven't seen the film, though, so I won't claim that I am able to judge the performance.
I feel I am in no position to pass any judgement on the years films and performances yet, as so much stuff will only get here next year (No Country, Juno, There will be Blood...). Anyway, interesting Top 5s by the guys, a lot of which I didn't see coming.
