Well, MarineGrunt, I won't bust your hump for watching movies. It's important to remember that they are "entertainment" and not reality. I like the Rambo series because they are entertaining. But it is not history.
A great book, "Stolen Valor", talks about how the average sheeple thinks all Viet vets are like Rambo, i.e., quite, disturbed, loners that are killing machines. He points out that the vast majority are just average Joes that came home, had families, and worked for a living.
But who wouldn't like a movie where he says stuff like" I'm your worst nightmare" and "I'm coming for you!" Great stuff.
On another note, you can get great movies cheap on a site called Half.com where you buy from individuals and they mail them to your home. I buy most of them for less than I can rent them and I then have a permanent copy. Try it.
