The usually dependable Bruce Willis (I’ve been a fan since “Moonlighting”) is flat here and he and Tracy Morgan have zilch chemistry. Morgan’s cop is simply too needy to care about. The only bright spot is Sean William Scott as the demented Dave. The plot (if you can follow it) hops from cliche to cliche, which is okay in a funny cop buddy movie. But when you enter that subgenre, you’re going to be compared to “Rush Hour” and “Bad Boys” and “Hot Fuzz,” so you’d better deliver on the =funny= and the =buddy=. This did neither. Director Kevin Smith’s fault? I dunno. I’ve already wasted too much thought on it.
