TV on DVD

I used to be opposed to the idea of buying a TV show on DVD. My philosophy was I've seen the episode, why do I need to see it again. That was until about two years ago when I was bored one weekend and on a whim bought the first seasons of Community and 30 Rock on DVD. Ever since I've been really into the concept. There are many things I like about TV on DVD. First of all, I learned that I really do like watching episodes of my favorite shows more than once. Yes, you already know what happens, but how is that different than watching a movie again? Second, it's much easier to see the whole concept behind a season of a show when it isn't broken up like it is when you watch on TV. Most shows really try to get somewhere in a season and you can see that development better when you aren't waiting around to watch them all the time. Finally it's a great way to spend a little time. I mostly buy sitcoms on DVD, so if I have a spare 20 minutes, I can just watch an episode and not feel to guilty about wasting as much time as I would if I were watching a movie.
