There was also something that bothered me: when they said the Kaiju had tried to invade the Earth before, they had to retreat because the Earth wasn't polluted enough. I didn't quite hear what the script said there, but it was either carbon dioxide or monoxide but both would be real pseudo-science.
Concentrations of carbon monoxide (which is quite shortlived in the atmosphere due to the huge presence of oxygen) and dioxide in the atmosphere were higher in the time of the dinosaurs. Carbon dioxide (wat most people would call 'the pollution') is at 0.03% of the atmosphere, but was considerably higher in the Jurassic period. It was at 10%. The time of the dinosaurs would be way better suited for an invasion.
The depletion of the ozone layer would also be quite stupid, in that case the Kaiju should be dying by the time the movie ends because it is estimated to get smaller and smaller by 2020 due to the regulations introduced in the 80s and 90s.
