A sequel to the film "Joker" has been released, titled "Joker: Folie à Deux", and it has received mixed reviews from critics. Some outlets have described the film as dull and misguided, while others see it as a thought-provoking sequel that questions the original's myth. The film's star, Lady Gaga, has reportedly laughed off the negative reviews, which some have described as "unhinged" and "backlash".
