I'm not a huge fan of Godzilla films, but I thought the premise is always that the monster attacks real cities (originally Tokyo, Osaka, etc.)

If you're going to depict a fictional city with buildings that defy the laws of physics, you may as well have it attack Gotham City or Springfield.

If we can accept the existence in a movie of a giant tyrannosaurus rex-like monster that is bullet and missile proof, awakened and powered by a nuclear bomb test and has "nuclear breath", does it really matter if the physics involving building destructing are realistic?

Well, I think what Moth3r is driving at is that if the world the giant fictional monster is in reacts realistically to the giant fictional monster, it makes the giant fictional monster easier to believe in.

I personally prefer a bit of stylized artistic license, for lack of a better term, when dealing with fantastical subjects. (like explosions and sound in space)
