I'll throw my hat in too. From what I've seen:
Life of Pi - would be one of the better BP winners of last decade or so
Amour - great performances, although I can't imagine it being an enjoyable cinema experience
Django Unchained - Tarantino shows his humanist side (by blowing himself up, of course ;) ), but I wouldn't call it an improvement over Basterds
Argo - well-made, neat dramatization, but ultimately too pedestrian for a BP win
Holy Motors tops them all for me - too bad it wasn't selected by the French Oscar committee, especially considering that Intouchables didn't even get the nomination.
