Coming more than a decade since the last franchise entry, Scream 4 again mixes murder, mystery and self-awareness, to adequate if not exceptional effect. A meta horror entry which reteams writer Kevin Williamson and director Wes Craven, the film introduces a fresh crop of victims and suspects, blending them together with old characters and past grudges, and succeeds on its own carefully prescribed terms as a piece of diversionary puzzlebox entertainment, but isn’t really very scary and doesn’t pack the wallop of the best moments of its forebears.
