It is not deep, but it is fun to watch. It does have a bit more of an edge to it than other similar films.

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."

If you like to be scared, if you like to laugh, and if you like to learn a thing or two at the movies, this absolutely cannot be missed.

Great story, amazing characters, superb action, enthralling cinematography. Yes, this is something I am glad I spent money on.
