Ful of plot holes

Rating: 6/10 (27 August 2014)

Good effects, bad acting, bad script, and oh the plot. I'm going to assumed you've watched the film and then go through some of the questions that I had.
So we never see the nuke get disarmed, and I'm assuming it went off, although they don't show this, which in itself is weird. How can what looks like a fairly slow boat have taken what we are told is an extremely powerful nuke far enough out to sea for San Francisco not to be totally fried, especially in the half an hour left on the clock? Even if it escaped the direct blast (which it wouldn't) the radiation would make it uninhabitable. And then how could the helicopter that picks up Brody have made it out of the blast zone in 5 minutes?
Further questions - why would you use planes against creatures that knock out planes? Why not bomb from 10,000 feet? Why would you put troops on a bridge where they are totally vulnerable? Why would you not use thermobaric bombs rather than nukes, and use them straight away, over the sea or desert, rather than waiting for everyone to converge in a residential area. Why give troops useless light arms. Why use a train to carry a bomb not a plane. Why put a nuke only 20 miles from a city, and then let it out of your control. How is there enough time to brief a new mission, fly a plane up there, drop troops, find a bomb and carry it to a boat, then drive that boat out to sea, in an hour and a half. Why set that time at all - why not use an unarmed one as bait, and drop another when the monsters go for it. If Godzilla is supposed to restore 'the natural order' when do we mean? Don't humans upset it? Why does Godzilla care? Are there no nuclear plants in Nevada - why would a MUTO travel to San Francisco, especially from a nuclear waste storage facility - surely they could meet there? Why would you put something you know feeds on radiation in that facility? Why not kill that one?
I get that I'm supposed to just switch off my brain and enjoy my popcorn, but seriously, it isn't that hard to write a story that makes a little bit of sense.
