A disappointing and unnecessary sequel 4/10 (SPOILER WARNING)
Pros:
* Phoenix and the cast were good as expected.
* Cinematography was great
* Some of the scenes in the court room were pretty good
* Great score
Cons:
* Terrible pacing and weak story. Almost nothing happens for the first hour.
* Harley Quinn was wasted in a small supporting role.
* The musical numbers were bland and added nothing.
* It made no sense why Arthur decided to stop being Joker suddenly.
* The ending was awful and made the entire movie a complete waste of time. We've followed Arthur for two movies only to find out he's not the real Joker and then gets stabbed to death.
