"The Green Berets."

Film is theater (or theatre, if you prefer). Aristotle discussed this in his "Poetics" and it hasn't changed since. Tragedy, comedy (meaning non-tragedy), farce, spectacle -- it's all there and it's all here.

I think that the problem is that today we blur the line between entertainment, the catharsis of theater, with reality. More, we view reality through the lenses of our own prejudices and preconceptions which have been at least partially shaped by ubiquitous entertainment. Perhaps we should reserve entertainment -- movies, television, etc. -- for special occasions held only a few times a year.
