Joker: Folie Deux has been perfectly summarized in a 2-minute LEGO fan-made DC animation. Joker: Folie Deux earned mixed reviews after a short run in theaters, earning just $192 million at the worldwide box office and dividing fans. The controversial ending to Joker: Folie Deux saw Arthur Fleck renouncing his Joker mantle and being killed by who would appear to be the “True” Joker, leaving a sense of dejection among fans of the first movie. Other criticisms leveled at Joker: Folie Deux take aim at its slow pacing and relatively stationary setting.
