If you loved Missing, try Doctor
A bridge between a film you've already seen and one most people haven't. Doctor has roughly 3.7× fewer votes than Missing — 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 Kim Sung-hong, and they sit in Horror / Thriller territory. If that's the register that drew you to Missing, the second film will land in a comparable space — through a different lens.
What Doctor is
Seoul, nighttime. A scalpel's glint. Sadistic surgeon Choi In-beom carves grotesque art on living flesh, while his beautiful wife soon seeks an impossible transformation of her own. Body horror goes under the knife in this nasty Korean thriller.
