I know why this movie gets so much hate.
We're living in a time where it's popular to hate white people and their whole history. The reason this film gets so much hate is because it's incredibly awkward for social justice warriors to have to face the fact that:
1. In WW2, the Japanese (non-white people) committed some of the worst atrocities known to human history, every bit as bad as the Holocaust and the crimes of Genghis Khan. This is awkward for the SJW's because they like to pretend only white people ever did bad things.
2. The USA did the world a huge favour by stepping up and making huge sacrifices to end the horror that was Japanese imperialism. This is also awkward for SJW's because they like to pretend that America never did anything good.
And so, the SJW's find any excuse they can to insult this depiction of young American heroes sacrificing themselves by the thousand to save the world from the horrors of Japanese imperialism.
Yes that is me in a blonde wig. Don't pretend I don't look sexy af.
