Maybe this is just because of where I am in life, but between work, children, and hobbies, I don't have time to be bored. If I'm watching TV it's because I'm choosing to do it instead of something else I should be doing or want to do. I will only even try shows that receive high praise from people I trust or from a lot of reviewers. If a show's only function is to kill time it has negative value to me.
