Actually, there's plenty of philosophical works that analyze zombie movies from various perspectives. They are still a product of human mind providing various excuses to kill humanoid creatures en masse, and we can use them as a mirror to peek behind the facade. You happened to see it without the candy wrapper of “it's just entertainment”, and the reaction was natural. In fact, trying to keep the face because “people around are having fun” would be the inhuman choice, just as the idea that people whose relatives are dying should better stay in hospitals and their own homes, and get some special “treatment” to keep others comfortable.

In the same manner, those who've seen the war may not react well the “Top Gun” style ass kicking with a happy end. There problem here is not within them.
