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."

A film of deceptively outspoken contemporary relevance, this is cinema at its most alert, alarming and alive.

There's a more than satisfactory amount of boom-boom in the movie's trim running time.
