Joker (out Oct 3) is a very different comic book movie in that it's focused solely on the "villain" with no mention of a hero. With a superb performance from Joaquin Phoenix, this is a grim, unsettling drama that you'll have trouble shaking off as you leave the cinema. A shame it's a stand-alone feature and not part of the DC Extended Universe as I'd love to see where it goes next. Grade: A-.
