Yes! Aardman captured our hearts with their _Wallace and Gromit_ shorts, and then, this film truly showed the characters at their highest potential yet. I especially love how expressive Gromit is without sound or a mouth. He's such a good, smart dog, too.
There's actually a difference between the original UK to the US version. Gromit is actually growing a large marrow, not a melon. They changed the dub because Americans wouldn't know what a marrow is.
21:48 "Has Gromit ever made a sound?" He has yelped twice, once in A Grand Day Out, and again in The Wrong Trousers, I'm not sure if he's made any other sounds though.
Actually CGI 3d animation costs a LOT more then stop motion animation, and really to do GOOD CGI animation (like at Disney/Pixar Dreamworks standard) takes just as long. Stop Motion animation only doesn't make as much because of bad marketing or audience taste.
