Damien Chazelle, the youngest director to win an Academy Award for Best Director with La La Land, has released a new film that has shocked many viewers. Some might describe it as a “vulgar black comedy version of Singin' in the Rain,” depicting the shift from silent films to talkies in a deliberately crude, tasteless way. Still, this boldness and “filthiness” are so purposeful that they become strengths of the film.
