Why so PC with the Japanese?

I never got why despite the fact that it was the Japanese that attacked us at Pearl harbor and brought us into WW2, in a cowardly surprise attack no less, Hollywood is always so sympathetic in their portrayal of them compared to the Nazis, when the Japanese army did similar things and were equally brutal and genocidal. All the Japanese war crimes like the Bataan death march seems overlooked as well as the Japanese war crimes in Asia. I saw the first two episodes of the Pacific and they already tried to humanize the enemy with the doll and they portrayed the American soldiers negatively in my opinion. I don't know why most movies dealing wih the Pacific front aren't as clear cut good vs evil as movies depicting the war in Europe when both fronts should have been depicted similarly. The Japanese were as evil as the Nazis and were a brutal and savage enemy with the kamimazes and suicide charges. Letters from Iwo Jima is another blatant Hollywood attempt at making us sympathize for the enemy.

I did like the general's speech in the beginning about keeping the world from being enslaved but there should have been a larger focus on Pearl Harbor and its affect on the American people and the patriotism it stirred up. It alsso would have been better if the doctor opposed his son going to war because he was an unpatriotic liberal who was against the war despite Pearl Harbor (the way many liberal traitors opposed the Afghanistan war after 9-11) and not because of his history with WW1 just saying. I still have to watch Band of Brothers but I've heard its more patriotic and pro-American than this one and is more clear about the good vs evil fight that WW2 was and it certainly was a fight between good and evil in both the Pacific and the European Western Front (I guess with the Eastern Front in the USSR it was evil vs evil).
