The performances transcend the film's tropes, grounding it in characters that feel more complete than this subgenre often produces.

A film with more than the usual spoiler issues. Talking about it in any detail feels akin to handing you a gift-wrapped present and saying, "I hope you like it -- It's a thriller about a diabolical secret experiment."

The film's masterful storytelling did its job. The message was clear. No need to overdo.
