It had a lot more to do with it being a huge Jurassic Park ripoff and having very little thematically in common with Godzilla. It wasn't a bad film. Just wasn't Godzilla.
Godzilla's also about this menacing almost force of nature that is unstoppable. If he's the antagonist in the film he should be wiping out the city, demolishing everything, using his atomic breath to set the world ablaze, everything in his path completely annihilated. It should take near an act of god to stop him. Godzilla's a monster, not a dinosaur.
