Extraordinary acting! I didn't understand the violence; this isn't typical with dysfunctional personality disorder (split personality), or is it?
Although, the main character's introverted behavior would indicate one should be cautious of him, yet, none of the town's people or neighbors were. This, I find odd, since; here's a man that lives in his childhood home with the curtains drawn closed all day, which, was more than just eccentric. Additionally, no one knew his mother. The actors portrayal made me question why no one seemed afraid of him because I could sense something might happen (don't want to give it away), which adds to my exceptional acting critique. The direction was also stellar, scenes did not have excessive gore or tormented flashbacks but the audience still knew what caused this mans psychosis. - Would love to hear if anyone else had the same questions.
