DOG: For connoisseurs of gore, Piranha 3D’s trashy combination of titillation and comic evisceration will make for an entertaining night out at the movies – if the idea of a CG fish puking up a half-chewed penis directly into the screen sounds like a funny gag, this is probably the film you’ve been waiting all summer to see.
For everyone else, Aja’s aquatic horror will prove a predictable, if mercifully brief, bore with jaws.
