Tough, he won, move on
He gave a great performance, he delivered an amazing speech. He didn't campaign for himself, we saw little of him during the awards circuit with the exception of when they called his name. He's a humble actor who speaks highly of other actors and I'm glad the underdog won out. Stallone gave a great performance. You almost forget he was capable of doing that when he's starring in crap like Expendables or whatever else he's done in the past few years. Had he won it would have been a deserved win.
He didn't, so for his fans whining and bitching, get over it. In the end the better man won.
