I saw the trailer and was most unimpressed. The CG Garfield looked like it was designed by committee - they couldn't decide whether to stick true to the original design from the comics or to make it look more photo real so they compromised, and you've got this FUBAR looking thing, not making it fat enough in fear of being sued by fat people.
But hey, the Scooby Doo movie made money with that fine looking CG dog (FOR ME TO POOP ON!) so kids will eat this one up too.
