I happen to think Patrick Tatopolous's Godzilla design is superb. No, it doesn't look like Toei's Gojira, but so what? As I said, difference from the source is not in and of itself a fault. The Batmobile from the 1966 sitcom and the Batmobile from Batman: The Animated Series look nothing like any prior Batmobiles from the comics, but they're both gorgeous designs. Grace Park looks nothing like Herbert Jefferson, Jr., but she made a pretty effective Boomer.
Although I actually think Tatopolous's creature worked better in cel-styled 2D animation on the TV series, where you could make out its lines better, than it did in "live action"-styled CGI in the movie.
