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."

It's funny, it's tense, it features two great performances from two actors and the director expertly creates a web of odd tension where you actually don't know what is happening for the majority of the run time.

The movie really just wants to entertain people.

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.
