Cop Out has a few laughs, but otherwise it's a surprisingly bland experience. It suffers from a generic storyline, questionable performances and the simple fact that almost none of the intended sources of humour achieve the desired effect.
Bruce Willis (an old timer) and Tracy Morgan (a new timer) are an odd couple indeed, but they had potential. The problem is that their levels of commitment to the film are polarized. Willis seems lazy and uninterested never putting much effort into it. Morgan on the other hand, tries way too hard. His larger than life style of crudeness is more clumsy than funny, and he upstages pretty much everyone else in the cast.
After about ten minutes, we have a pretty good idea of how this film is gonna play out, but we go with it in the hope that the trip is worth while. Unfortunately there are more silly contrivances and poorly written lines than there are laughs. The only time when Cop Out is funny (and remotely clever) is over a Good Cop Bad Cop routine that Willis and Morgan have. There are enough action movie jokes to make it clear to the audience that at least Kevin Smith has the self-awareness necessary for satire. But from what I saw, Cop Out isn't really a satire at all. It no better or worse than any other failed cop/comedy. I'm not sure if it's laziness or lack of thinking behind it, but Cop Out hasn't got the goods
