127 Hours is a firm last in my list, of those I've seen.
I'd probably have it in this order:
Inception
The Kings Speech
Toy Story 3
The Social Network
The Fighter
127 Hours
None of them are bad films, mind.
I'm a massive Coen Brothers / Jeff Bridges fan, so I can see True Grit jumping to the top of that list, if it meets expectation. The Johnny Cash trailer alone is almost Oscar-worthy.
