Is this intended to be an African American take on "Cagney and Lacey"? I'm thinking there was a cop from a wealthy family partnered with one from a more modest background. Here, Will Smith portrays the polished and self-assured “Mike,” who is paired with “Marcus” (Martin Lawrence) in the narcotics division. Following a daring raid that empties the police station’s evidence room of millions of dollars' worth of heroin, it becomes their job to discover who was responsible. Surely, finding the culprit shouldn’t be too difficult—that's a huge quantity of drugs, so only a few people could possibly handle it. Their informants quickly provide them with a key piece of information, but not before several casualties occur and “Julie” (Téa Leoni) needs to enter witness protection. Adding to the confusion, she believes “Marcus” is “Mike,” forcing him to pretend and move into his friend’s apartment, much to the annoyance of both "Mike" and his wife, “Theresa” (Theresa Randle), whom he deceives by telling her he's gone undercover. What follows is a buddy comedy with occasional bright spots, but it suffers from some truly uninspired writing and villains who are about as intimidating as leftover pizza. The final twenty minutes or so pick up the pace considerably, featuring plenty of explosions and demonstrating how quickly a Porsche Boxster can accelerate, though overall this feels like an uninteresting relative of “Beverly Hills Cop” (1984), with some stronger language. It’s remarkable that Leoni manages to be somewhat likable here, but thirty years later the film has become dated and lost much of its original appeal, especially considering Lawrence was at his peak comedic ability and "The Fresh Prince" still had a certain novelty. It's adequately entertaining, but not particularly inventive.
