I caught of screening of The Master last night, and I've been trying to collect my thoughts on it. I've come to the following conclusion:
You know that scene where Dodd has Quell touch the wall and the window over and over again? Dodd is PTA. We are Quell. He's fucking with us, laughing as we try to make something significant out of nothing. That scene is a metaphor for the entire movie.
Also Amy Adams is kind of scary.
