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."

All that we are seeing on the screen is happening with real people, real action sequences in the background, forcing the eye to watch as if we were there.

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.
