It’s been nearly three years since Westworld was canceled by HBO, but Apple TV+'s Murderbot is an ideal replacement. Taking place in the future, Westworld is about an adult theme park made up of android hosts who exist solely to entertain the Wild West fantasies of their human guests. Westworld introduced new theme parks and changed the setting to the outside world in later seasons, and its cancellation caused many fans to miss coming up with Westworld theories.
