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 movie's neither hopeful in contrived ways, nor hopeless in different contrived ways. Somehow it manages to be wonderful

The tone of this movie is interesting -- the stakes are both dramatic and high, but it's balanced with a lot of fun, tongue and cheek dialogue.

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