If youโ€™re a fan of Will Arnett, Tracy Morgan, or Zach Galifianakis, be prepared for disappointment: They arenโ€™t funny in G-Force. Their boisterous personae are all obscured by gobs of Disney Channel Spackleโ€”that plasticizing Tinkerbell-churned formula that murders any shred of risk or invention while ensuring predictable opening-weekend returns. And judging by the tepid reaction from the kids in the theater, it seems they got less than they expected.

Itโ€™s a movie about a secret Homeland Securityโ€“funded group of three guinea pigs and a mole named Speckles (a shamelessly nerdy Nicolas Cage). They were trained by a brilliant scientist (Galifianakis) โ€œto do in one night what it would take the CIA two years to do.โ€ Namely: foiling a corporate evildoerโ€™s plan to transform all the appliances in the world into an army of Terminator coffee machines. The G-Force has cute little infrared goggles, mini grappling hooks, and a โ€œpimped-outโ€ hamster-ball ATV, but when theyโ€™re mistakenly caged up in a pet store, itโ€™s up to their wits and their โ€œstrength as a familyโ€ to save the world.

Youโ€™d think megaproducer Jerry โ€œthe Blockbustingโ€ Bruckheimer would have ordered some more set pieces to blow up or okayed a less painfully benign script for his first 3-D movie spectacular. Instead, he wastes a crew of talented actors, teases with infrequent action, and insults with dull, safe humor. Donโ€™t worry, aspiring filmmakers: The talking-guinea-pigs-that-fight-crime market is still wide open. recommended
