Movies and music are usually made to be entertaining, but sometimes they're made as an artistic outlet for the creator.

I was listening to Schoenberg's "Suite for Piano" the other day. Did he make it to be entertaining? I don't know, interesting maybe. I wouldn't put it on at a party.

It's true that snobbery is off-putting, but if you're looking for artistic merit, then some works last longer than others. If you're looking for something to enjoy with your popcorn, then there's that too.
