Stephen King's Castle Rock sounds like a fun town to visit, but you probably wouldn't want to live in a place where literal and figurative monsters abound. Between 2018 and 2019, Hulu produced Castle Rock, an original series that gave King's books the shared universe treatment they've rarely received in live-action. Later this month, Castle Rock is moving to Netflix for a chance to scare up new viewers six years after the show's conclusion. Now, Watch With Us is sharing the reasons why Castle Rock is the one Netflix show in December 2025 that you have to watch.
