The only thing I really disliked about this movie is how they had to do the usual American film thing of killing the bad guy/monster, and worse yet, how they completely destroyed the possibility of Godzilla being a somewhat sympathetic character (something that at points they hinted) by making it shoot infinite babies out of its ass and the usual "at this rate it will end the world in a week!".
There was potential for a giant monster franchise similar to the original Godzilla movies. Just introduce the monster, have the military fight it, have the good guys make "friends" with it, have it apparently die in the end (but the good guys know it hasn't). Then make a sequel where some other bad monster shows up, and the good guys go recruit Godzilla to kick it's ass. Rinse and repeat.
But no, it had to be a lizard alien queen with infinite broods of fattyraptors. Oh well.
