Impressive.

I saw "Platoon" on my first date; not the guy's best choice.

I think you did an exceptionally good job explaining how the Vietnam War contributed to the change in drug use beginning in the 70s.  The images in Platoon sometimes haunt me still (even though I've never seen it again and don't plan to) and definitely show why people would go to such self damaging lengths to escape the reality they had experienced in Vietnam.

What scene was most striking to you?  Mine was at the end, when the main character flies away and starts to cry.
