For me one of the best examples is American Horror Story. I don't think it's an amazing show, even though I liked some of the things they tried with it in the first couple of seasons. But season 3 - didn't do jack for me. Nothing scared me, nothing interested me, it was just a drama season with some witchcraft. But I know some people loved it. It's all about what best gets your heart racing, what makes you think over and over about something you don't really want to.
