yeah, want a good example?
Well, maybe only you anime freaks like me may actually go out and get it, but do look up for a copy of "The Silent Service" (based on WW2 submarine in the pacific).
Japanese version is... i'd say, realistic and to the point, actually capturing the feelings of hatred of the enemy , duty, fear, etc of a crew of a sub... the anti-american language is obviously strong and biased, but then again, so is what the american characters say about the japanese in the movie!
Point is, watch it in the original subtitled or dubbed IN JAPAN version, then watch the dubbed/subtitled in the US version. The censoring and mass-appealing, money grubbing marketing "editing" (just like those multiple endings in pearl harbor to not "offend" foreign costumers) to make it a lame action anime for the us market is simply pathetic.
