Joaquin Pheonix was absolutely incredible in his performance of the Joker to where the mental issues and social issues he dealt with are so believable with his acting of his character. It's awkward to watch at times but it grips you during the entire movie to where you just can't look away. Is a very dark themed film and a few of the killings are VERY graphic and one in particular is VERY shocking. Different than most movies I've ever watched in that the movie is all about his decline and ends with him simply identifying and becoming the Joker. But definitely an incredible movie and worth the watch for DC and Joker fans!
