An irreverent reboot of the late 1980s TV series that helped launch the career of Johnny Depp, 21 Jump Street only half-heartedly scratches the surface of the more intriguing comedy of young male anxiety at which it hints, preferring instead to target broader laughs. If it gets bogged down a bit in its dutiful inclusion of procedural and action hijinks, the movie still sails on the strength of some of its joke writing, and the chemistry and smart use of its stars, Channing Tatum and Jonah Hill.
