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."

Excellent and certainly provocative... If nothing else, the film is a real conversation starter.

One of the most extraordinary films you will see this year. Take that as you want.

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