The film makes a home in your brain and the only cure is to see it again.

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."

This movie tries so hard to be funny, yet it falls flat every time. Just another example of recycled ideas repackaged with women in an attempt to appeal to a certain audience.

The film never slows down or bores, plunging from one harrowing sequence to the next.
