Homunculus (2021)

Homunculus is the kind of psychological thriller that grabs you with a dare: what if one small, impossible procedure cracked open a new way of seeing people—literally—and you couldn’t look away. Takashi Shimizu turns a wild premise into something surprisingly intimate, using eerie imagery and a slow-burn, off-kilter mood to probe how trauma warps the stories we tell about ourselves. Go Ayano carries the film with a haunted, grounded performance that makes the surreal feel uncomfortably plausible, while the movie’s best moments land like unsettling observations you recognize before you can explain them. It’s not for viewers who want tidy answers or conventional scares, but if you’re drawn to strange, thoughtful horror-adjacent dramas that linger in the mind, this one is worth the plunge.

Homunculus is clearly aiming for a grim, psychological deep-dive about trauma and identity, using its trepanation hook as a gateway into people’s hidden damage. The problem is the film often feels like it’s borrowing big, edgy ideas without shaping them into a coherent, satisfying story, so what should be unsettling and insightful can come off oddly silly or half-baked. The effects and “homunculi” imagery have moments of creepy creativity, and Go Ayano commits, but the execution wobbles enough that the longer it runs, the less clear its point becomes. If you want a tight thriller with clean rules and a payoff that clicks, this will likely frustrate you; if you’re okay with messy symbolism and mood over logic, you might still find something to chew on.
