It's entirely possible that sending the audience out feeling lousy was intentional

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.

True to its essence, the characters remain on the same line and manage to entertain the viewer, each highlighting their own distinctive qualities or touches.

The tone of this movie is interesting -- the stakes are both dramatic and high, but it's balanced with a lot of fun, tongue and cheek dialogue.
