I still haven't managed to see Room but based on the book and everything I've heard about it, I'd be pretty happy if it won. But there are no real standouts in the nominees for me. Of the ones I've seen, Spotlight is the most deserving of best film.
I have seen them all except for Mad Max. Unfortunately, I loved The Danish Girl, which is not nominated. I am torn between Brooklyn, Room and Spotlight. And, like picking for the skating Prediction Website, I would stink at choosing, so I won't.
(Bridge of Spies - 2nd choice).
I appreciate "The Revenant", but it is too much like a famous Soviet novel and movie "Tale of a Real Man" (Повесть о настоящем человека), plane crash, pilot survives but injured, broken/frozen legs, crawls home for days, lives.
