Allow me to be the lone dissenter.
We've seen this how many times before? You knew the ending before it began. The first 10 minutes were nothing but a swear fest. I can endure swearing, but every other word was from the gutter and served no purpose other than to hook the high school crowd. Fortunately, they toned it down the more it went on.
I spent the entire movie fantasizing about Mila Kunis. Not that there is anything wrong with that. I was able to fanaticize about her without the need to concentrate on the movie because I knew where this was going. The nice thing about this movie is it didn't require one functioning brain cell to watch.
The funniest parts were with Woody Harrelson and Richard Jenkins. Richard's were by far the best; I just liked Woody's outrageousness. Patricia Clarkson once again shows what a versatile actress she truly is. These three carried the movie, IMO. Mila - cute and sexy. Timberlake - nothing special. Both have done much better. In the end, my fantasy was much better than the movie.
