The movie concept was great. In fact the dinner with the schmucks was very funny, I just wish there had been more of it. Rather than concentrate on what the title of the film would have us believe the movie is about, it takes its time to get there. The movie is about the relationship of Paul Rudd and various people including his gf, ex-gf and Steve Carell, the schmuck he has selected to take to a dinner filled with schmucks. This is a monthly event hosted by his boss.
Steve, our schmuck, uses dead mice to make menageries of his life and the history of mankind. He is really a nice guy, who through his stupidity messes up the life of Paul Rudd. The movie makers decided the movie needed a heart warming message that schmucks have feelings too, not thinking that the audience doesn't really care. I think making Paul Rudd attend multiple parties, building up to this one would have been better than the trek these writers took.
The movie was funny when it wasn't overly stupid. The reason why we laughed at those Pink Panther movies because there was a sense of possibility in all that stupidity. When you cross that line to no possibility, as this movie sometimes does, it becomes just stupid.
Listen carefully to Steve Carell's lines as he mixes up words. "After sex you curl up and assume a fecal position." Funny without fart jokes. While the humor is adult, I wouldn't classify it as overly crude. Three and a half stars for sure.
