I'm surprised that The Descendants is on here, too.
It was one of the year's most acclaimed films, and won a ton of critics' awards (and Clooney just took the Golden Globe).
I've seen seven of the nine nominees at present, and will see the other two. Provisionally I'd rank them:
3. The Tree of Life
4. Midnight in Paris
5. The Help
6. Extremely Loud and Incredibly Close
7. War Horse
Without having seen the final two, I will say that this year's nominees don't feel nearly as good as last year's. The A-line of last year (The King's Speech
, The Social Network
, Toy Story 3
, True Grit
, The Fighter
) would probably all place ahead of Hugo
