“Cop Out” (2010) is a formulaic, stupid, buddy-cop movie starring Tracy Morgan and Bruce Willis. It is also funny and 10 times more coherent than many comedies that have come out recently. Witty banter. Plotlines that come together. Actors that appear to be having fun (They seem to understand that they are making a movie, not curing cancer.). Strong costars (Jason Lee, Seann William Scott, Kevin Pollack). A “Die Hard” reference. Morgan is kept under the necessary amount of control. Willis is aging well. File it under escapism. Watch it when you’re tired and need something easy on the brain.
