If you loved I Spit on Your Grave, try House of 9
A bridge between a film you've already seen and one most people haven't. House of 9 has roughly 10.5× fewer votes than I Spit on Your Grave — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Steven R. Monroe, and they both carry the gut punch mood tag, and they sit in Horror / Thriller territory. If that's the register that drew you to I Spit on Your Grave, the second film will land in a comparable space — through a different lens.
What House of 9 is
Nine strangers awaken in a mansion’s dead center, illumination too sharp, shadows too deliberate. A metallic voice assigns roles they never auditioned for. One by one the exits seal shut. A sleek slaughterhouse hommage for the reality-TV age.
