at the beginning it was classical anime it has some good points but the development of story didn't change at all
most of my family are doctors (exp me i am engineer XD) so i know some basic about that job so after each ep the realistic of the anime decrease something like " he did it by himself with out any help at first time " is something that impossible
at the natural station maybe i will give him 5/10 but that wasn't the case in here because the anime just take some politics issues and present it by very bad way
yup i mean Vietnam war the anime used the same concept as the USA media just tell the people how good they are
just in the anime : War crimes are done only by Vietnam side , USA was just there for spread flower nothing else , USA used air force most of time to destroy everything include the target and anything who just around them and more
here is some facts u can find it by 2 min search :
"A large number of war crimes took place during the Vietnam War. War crimes were committed by both sides during the conflict and included rape, massacres of civilians, bombings of civilian targets, terrorism, the widespread use of torture, and the murder of prisoners of war. Additional common crimes included theft, arson, and the destruction of property not warranted by military necessity."
i am not here to say who is right or wrong but don't stuck politics issues if u want to just lie about it and didn't show the whole picture
someone will say "man that isn't political program to do that " well u r right that was just anime so don't talk about political , if u want to do that just convert it to political program that no one will watch it
