I don't have anything left in me to write a review. This movie leaves you drained in a way no other movie can. An extremely twisted take on revenge.
All actors put in brilliant performances and the characters transcend the story. The movie will always haunt me no matter what. I read somewhere on Letterboxd that people who see this for the first time need therapy and I agree.
If you don't mind watching a revenge movie that is extremely twisted, and very violent (mentally and physically) give this a shot. A masterpiece.
