There were those sad movies about kids in war time too.
No, the war was not unambiguous cool good as far as I remember. I never perceived it as cool technology only, it was never framed to me that way.
My grandma used to say that war is horrible. The grandparents generally did not liked it and did not liked movies with shooting and bombing. They added details only later, the stuff they personally seen, when I was adult, but when I was kid they would at least generally say it was bad.
