People who have Beverly Hills Cop and Miami Vice encoded in their nervous systems and are looking for restimulation may be amused by this formulaic sass machine and police procedural, but I was writhing in my seat. Martin Lawrence and Will Smith play undercover Miami buddy cops who briefly exchange identities while holding a witness (Tea Leoni) in a drug murder under wraps, and the banter is so heavy that the movie seems to be doing all your laughing for you. The cops never seem to know what they’re doing, but then neither do the filmmakers, though I can’t imagine that casual audiences will care since there are plenty of big explosions at the end to reward them. Directed by Michael Bay from a script by several hacks; with Tcheky Karyo and Theresa Randle.
