10 Stephen King Movies Worse Than the Books, Ranked

Collider ranks ten Stephen King movie adaptations that are noticeably worse than the books they were based on. The piece highlights common problems: films streamlining plots, altering endings, or changing structure in ways that reduce the novels' impact. Examples discussed include The Dark Half (which works decently but is weaker than the novel), Doctor Sleep (ambitious but less consistent as it tries to reconcile the book and the earlier film), The Running Man (2025) (captures the spirit but loses some of the book’s visceral desperation), The Dead Zone (streamlined and somewhat slow), Needful Things (whose escalating build works better across hundreds of pages), and Cujo (which softens the ending and loses impact).

It Chapter Two is criticized for the decision to split a novel that cuts between young and older characters, making the second film feel repetitive, and Pet Sematary’s film versions are said not to match the book’s blend of terror and sadness.
