Lack of good storyline.

everything you have heard about this movie is true.

I wanted to like it more than I actually did... But much of the humor totally escaped me and I walked out only mildly impressed.

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."
