I think TV makes people idle, and distorts their sense of reality. I've heard kids saying things like "remember the one where...?" when they're talking about real-life happenings; like life is a TV show. I'm not too old, but I've noticed this, and to avoid wasting my time, money, and welfare, I avoid watching TV.
We cut Netflix down to two movies a month and that is more than enough for us at this time of year. I'm learning to become more selective in what we get from them and how to find what we both like to watch.
