It seems as though Hulu fan-favorite show Castle Rock has been canceled after two seasons.

Castle Rock is an anthology series focused on the fictional town in Maine of the same name. This series drew a lot of inspiration from Stephen King stories like Misery and Shawshank Redemption.
In April of this year, Castle Rock producer J.J. Abrams and HBO Max joined forces to develop a new project called Overlook. There is speculation that it would be similar to the Castle Rock aesthetic and The Shining universe will be the inspiration, centering around the Overlook Hotel. Looks like fans will have to jump to HBO Max to get their Stephen King horror fix for now.
