Decent movie, impressive plane combat scenes (makes me want to rewatch Masters of the Air).
Dialogue felt like it was written by robots but it's Emmerich so didn't expect anything there.
What I really liked about this movie was that it showed a part of WWII that is so overly ignored, it's absurd. During WWII, Japan was engaged in the Sino-Japanese (China-Japan), as Japan was invading China was resources and whatever else they could get.
The treaty of Versailles screwed Japan, despite their role in WWI, so that is why they joined the nazi's (lowercase on purpose, I'm Jewish, and my family comes from Poland around 1946... yea, exactly) in WWII, hence why when the American pilot that was captured by the Chinese soldiers asked if he has bombed Japan, and after confirming, he immediately shook the pilots hand.
It's crucial to understanding the current world political landscape, as think what might have happened if China wasn't as vulnerable after the years of invasion by Japan, and Russia came knocking with the promise of the Utopian Idealism of Communism. Yes, I am summing this up so stupidly simple it skips extremely major points, but enough for a movie review ;)
Edit: I will add that the poor CGI in at the beginning in particular... it really takes away from what happens during the first attack, as I am looking at this sailor, but all I see is horribly awful cgi fire on the guys leg, who doesn't even seem to notice he was on fire...
