Tried to sit through both these films. Just couldn't get interested enough. The Humbling was still watchable for a while, but then it just got too boring and I stopped caring about what's happening.
Birdman - I couldn't care less about what was happening with the characters (not a single one of them). Found it boring / idiotic from the start.
Guess this makes me a philistine. Sigh… oh well, shit happens.
