It's funny watching the elements come together in this complicated scam. On one hand, the set-up isn't quite as complex as it seems, but there's an easy sense of fun in every exchange.

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 creates a perfect balance between action and depth of basic needs, in the midst of an infertile atmosphere.
