I thought the movie was rather boring to be honest. The entire first hour was a waste of time: did anyone not roll their eyes when the wife dies up against the glass in the power plant? Could a movie death be any more contrived? Also, what was up with the train/bridge scene? You have this massive warhead and you send it by train with 4 marines to guard it? Even when you know the monsters can detect nuclear sources? And then you arm the bomb on the boat in the harbor!? Everything around the Godzilla was so dam stupid.
The EMP wouldn't allow them to carry it any other way, so they used the train, and I assume most of the Military was trying to keep the monster at bay
But after the train crashes they come in and pick up the bomb on a helicopter............
......and put it right on a boat which can be shut down by the EMP, which is exactly what happens after they arm the bomb in the harbor. Not sure if there is anyway to spin that entire sequence without using the word "dumb" in some fashion.
