More grotesque is Splinter, their rat "dad," who looks like Dustin Hoffman as a werewolf. He and the Turtles get some violent treatment by the Foot Clan, which may be disturbing to tots. Bursts of gunfire hitting the bulletproof turtles get nastily amped up, too. The film manages to bungle the first time we hear their attack call, "Cowabunga!" (Since the turtles sound like they have seaweed in their mouths, you can't make out what they're saying half the time).
