This is a polarising movie. You'll either find it a masterpiece or nothing. Personally this is one of the greatest movie I've ever seen in my entire life,all thanks to casey affleck's oscar winning performance. Only hardcore movie fans who still believe in raw cinema and pure acting would understand what I'm saying if you're just a casual movie watcher I'd advice you to stay away from such movies cuz these kinds of movies represents true and purest form of cinema.
