It's hard to disagree with the assertion that it separates the family. However, I do know families that watch all sorts of programming together. This would seem like a great way for parents to gain insight into what their kids like and dislike, as well as how they view the world. Yes, obviously they could just ask their kids at the dinner table, and that would be the best place to start. Yet, we sometimes have trouble communicating the more subtle aspects of ourselves.
TV takes on a whorish existence in our culture.
It's cheap and easy, and can get out of control with little effort. It is, though, part of our culture in the 21st century. Whether you own a TV or not, it has an effect on you because it affects others. If you watch a lot, try stepping back. If you never watch, give it a try.
