Collider has published a ranked list of the best R-rated horror movie trilogies, highlighting franchises that manage to sustain tension, identity and thematic depth across three films rather than simply repeating scares. The piece argues that strong horror trilogies need genuine progression between instalments, and singles out series spanning action-horror, teen slashers and character-driven psychological horror.

– The Blade Trilogy (1998–2004): Wesley Snipes stars as the vampire hunter across three films, with Guillermo del Toro's sequel adding creature horror before a messier third instalment.
– The Original Fear Street Trilogy (2021): Netflix's Leigh Janiak-directed series, based on R.L. Stine's books, released three films across consecutive weeks, weaving together timelines from 1994, 1978 and 1666.
– The X Trilogy (2022–2024): Mia Goth leads A24's series (X, Pearl, MaXXXine) exploring fame, ageing and self-invention through women defying the lives expected of them.
