It’s an especially fun movie from a director and cast who are clearly having a good time allowing themselves to let loose.

It's hard to see any effort in the film. There's no comedy to speak of, no real drama and, worst of all.

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."

Exactly the movie you think it is, but not the movie you want it to be.
