This is a tender, generous movie that likes its characters and presents them as real people, full of flaws and strengths.

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."

One of the worst ways to make a cult movie is to set out to make a cult movie.
