Fanciful, disturbing, and wildly original, it announces the arrival of a fresh, bold voice in American cinema.

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 acting is good, and the firecracker script has some excellent ideas.
