This is a dark, weird movie, masterfully acted by Phoenix. He had a similar, dark, disturbing role in "The Master". This movie is much like that one, in that you find it disturbing, and don't care to watch it again because it doesn't leave you feeling good at the end. But the acting in both of those films is incredible. Kinda of feel spooked out after watching it. How many of these types of crazies are out there, one word away from snapping? Probably more than we would ever want to know.
