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

In truth, there is barely enough story here to make a film.

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."

This is one of the best movies I’ve seen in a very long time. You have to go and see this on the big screen.
