I concur, it was crappy!
Just because the government decides to fight a war doesn't mean that you have to agree with it. Especially a war like the Vietnam War which is one of the biggest mistakes this country has ever made.
At least John Kerry served in battle situations and has empirical evidence as to why war should be entered into cautiously (A point also made by Colin Powell)
As far as the comments "John Kerry's speech defined Vietnam Veterans as drug users, murderers, rapists, and psychopaths.", history backs up these statements ( although not everybody was like this, but certainly many were)
This movie was misleading and dull and THAT is why I can safely say it was crappy.
