Based on a bestseller that had a few chapters that were screaming funny. Somehow, this just did not translate into a great comedy movie. I consider myself right in the wheelhouse of the target market too; loved The Hangover (R-Rated Single-Disc Edition), Naked Gun, Monty Python movies, Jim Carrey fan, Animal House, etc.
I found myself in scene after scene trying to like this because of the book. That should never happen, and did not bode well. To be polite, this movie had a few moments. To be honest, it was sophomoric and forced, and painfully unfunny. Not even a grin. Not once. Fast forwarded through more than a few scenes. May have to retaliate next year for getting this as a Xmas present.
