Based on nominations and current awards, I see Argo & SLP having most momentum splitting votes (Argo not getting a BD nod is still puzzling) and Lincoln coming in winning BP in a really close vote.
The reaction with the kid at the end of Looper keeps it off this list for me where he goes all X3. My friends and I blurted out laughing (we were pretty put of it) in an otherwise mediocre, boring flick.
Just an FYI, obviously it's fiction. However everything is set up with the facts of what happened (that Mark Boal found out with who he talked to in CIA). I thought it was powerful, exhilarating, with a perfect end point.
