if their story seems completely bonkers, almost like a feverish work of fiction, you ain't heard nothing yet.

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.

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.
