This is a classic case of the trailer giving away all the best parts of a movie. Typical of most comedies lately, all the moments that make you laugh out loud are given to you months before you take the time to see the movie, and you don't laugh out loud. Granted, the cast and the situations do bring a great deal of unexpected and random humor, but in the end I got exactly what I expected.
All that being said, it is definitely worth spending some time on the couch and watching this movie. If you need something light and easy and a bit off center to kill a couple of hours, this will suit you just fine. Mike Tyson brings the best cameo performance and I love the chicken.
