Vonnegut.

I dont understand the definition of art which excludes most films ever. If its a man made form of expression, you can generally say its a piece of art.

I guess the term is very nebulous. We still use the word as a way to describe all visual media, even though one would also call writing and music art as well.

"Art form" is even more vague. Making good food is an "art form" even though a chef is more of an "artisan" than an "artist".

Semantics.
