Unfortunately, one lame Die Hard joke in the excruciating opening sequence is as self-aware as Cop Out gets. What's worse, it doesn't even satisfy on more basic levels: the action scenes are too simple to be exciting, the comedy barely even registers.
Kevin Smith's take on the interracial buddy-cop movie craps out, leaving Tracy Morgan waiting for the ideal big-screen vehicle and Bruce Willis treading water between the action-hero and character-role phases of his career.
Cop Out plays like one of Steven Seagal's recent DTV offerings; where the plot doesn't make a lot of sense and exposition is handled in voiceover, suggesting that the movie was never really finished -- just that the accountants told them to stop shooting.
Smith's directorial style is far too slack for this material, which aims to be an homage to populist '80s classics like 48 Hrs. and Lethal Weapon, but only winds up resembling one of the bargain-bin knockoffs that floundered in those films' wake.
