It is hard to recall a series that has experienced such a spectacular debacle as The Witcher. The adaptation of the saga, based on the epic fantasy books by Polish author Andrzej Sapkowski and popularized by the video game version, started in 2019 as one of Netflix's pet projects. It sought to be the platform's equivalent to Game of Thrones, forging a franchise with multiple derivatives. It's the kind of thing Netflix has struggled to replicate since Stranger Things.
