But years before Welcome to Derry, another series did the “world of Stephen King” anthology show in a far more ambitious format — and you can watch both bone-chilling seasons on Netflix. In 2018, Hulu released Castle Rock, a horror thriller series with a fascinating premise: most of the cast had previously starred in a different Stephen King adaptation. The series recognizes that TV episodes aren’t just chapters in a book; they’re self-contained works of art. Now that it’s streaming on Netflix, a new audience — and a newly-educated wave of Stephen King fans — can discover it all over again. Castle Rock is streaming on Netflix.
