Nothing in this film is authentic...
...and that's FINAL.
Seriously, it pains me to see people believing they're looking at the difference between two cultures, when one is not even close to the actual thing - Japan.
Sure, Japanese may seem more serious about work than some countries (especially since this was the 80's), maybe even too much considering few people even die from stress at work, but you all have to understand that superiority can be more demanding in Japanese culture (of course you also have to understand that what one person says never applies to all, but trust me on this one). Someone older or higher in rank, you have to change most entirely how you speak with a different set of words. But that's Japanese culture.
This was obviously too hard for the filmmakers to grasp as they did an extreme interpretation of the so called "Japanese way". This is exactly why this film is so crazy! They didn't even use a single actor/actress who's first language was ever Japanese (oh my god, you wouldn't believe how much their Japanese didn't make any sense. I mean NONE OF THEM were legitimate Japanese actors).
Anyway, I don't mean to agree at all with anything in the film because the American culture's interpretation was done extremely as well. I also don't mean to dis' any side of either culture. I just mean to tell you all that, please DO SOME RESEARCH!!
I know Hollywood films can't ever be trusted, but by far "Gung Ho" is the worst and most painful stereo-typical films I have ever seen in my entire life. I'd say a 5 and a half star rating is already over-rated, but that's all your choice.
I just want to urge you all to not believe everything you see and make assumptions based on what you see, because nothing defines ignorance more than that.
