In August 2022, amidst a bevy of other cost-cutting but callous decisions, Warner Brothers Discovery began removing shows and movies from HBO Max that couldn't be found anywhere else. It wasn't subtle; dozens of titles disappeared across the course of the month, including "Vinyl," which was created by Martin Scorsese, "Mrs. Fletcher," starring Kathryn Hahn, and an inordinate amount of animated and kids' shows. The streamer didn't stop there, though. By December, one of its former flagship shows, "Westworld," was gone, along with a total of 80 other movies and series according to IndieWire.
