The idea of doing a dirty Lassie movie is wittier than its execution in this go-for-the-gonads sci-fi flick about a huge guarddog named Max who becomes ultra-possessive of a feckless TV reporter (Ally Sheedy) after she springs him from an animal-experimentation lab.
The GuardDog also speeds things up by letting you crank drives through a mechanism that'll wipe them as they pass through, even if they're enclosed in metal cases.
