I've always loved movies and movie trailers, so I like to frequent Apple's Movie Trailer site. I'm increasingly amazed at, not only how many movies I have no interest in seeing- but how many I would actively AVOID if they were to appear on my TV during a channel-surfing session!
Sure, some of them look mildly interesting and there are a couple that I'd actually go to (or have gone to) the theater to see , but it's pretty thin gruel.
Bottom line: I want to be entertained, inspired, amazed or deliciously terrified. Unless I'm watching a documentary, I DO NOT want to be indoctrinated, disgusted, depressed or otherwise uncomfortable.
