This is a Paul Schrader movie which means it's about the nature of morality and spirituality. It's a character study of a man played by Oscar Issacs who was deeply damaged in the Iraq War and is troubled by extreme guilt. If you're looking for a fast paced caper about big time gambling It's not THAT movie. If you like a deeper story which makes you think about the essential nature of life and humans, this is for you. I don't why other reviewers said the acting was bad. They might have confused the acting with characters they just didn't care for. If you're a fan of Schraders other films , the films of Robert Bresson or Ozu this is for you.
