“Joker: Folie a Deux” (*1/2 out of four) was a terminally weird sequel to the 2019 original about Arthur Fleck/The Joker (Joaquin Phoenix) who is imprisoned at Arkham and awaiting trial for his crimes when he meets the love of his life in another inmate (Lady Gaga) as well as the music that will unlock his pain and set both of them free. Fans of the original (I wasn’t) may want to take a look but it’s awfully tough to take, with ridiculous musical montages and a story that is alternately bizarre and tedious. Phoenix is solid again and Gaga is strong but wasted.
