Simple and well acted, it has tension enough to knot the stomach.

When a movie has you begging for it to end not even half way through it's pure crap. We've all seen this movie and this characters millions of times, nothing new in it. Don't waste your time.

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 clunky actioner with a handful of cool moments.
