• The main character's enthusiasm to enlist is portrayed as irritatingly naive and ridiculous.
• The combat centers around the main character accidentally killing innocent villagers and a fellow American soldier.
• The main character winds up paraplegic, impotent, incontinent.
And all this happens before Willem Dafoe even shows up.
It's easy to see why someone would find aspects of 'Saving Private Ryan' attractive (eg: Private Jackson, the sharpshooter), and it doesn't require much imagination to see how aspects even of Nazi villains can be attractive (they had the best uniforms).
It's more difficult to see how 'Born on the Fourth of July' would leave anyone - even a sadist - enthusiastic about war.
It's not like Kubrik's 'Clockwork Orange' in which some of the violence, in a sick way, empowers the main character.
Instead, the main character pathetically bumbles into shooting people he doesn't mean to, is shot himself, and turns into an angry loser in a wheelchair (until he finds his calling as a peace activist).
And the fascists have the outfits
But I don't care for the outfits
What I care about is music
And the communists have the music
Great song thank you.
There have on occasion been wars that were fought over resources rather than for recreation.
Personally, I would also include Schindler's List.
