someone please explain to me why you would want to own dvds or have a dvd collection. even if i really love a movie, i can't watch it more than twice. i feel like i'm wasting my life away watching something if i already know what is going to happen. do those of you who own a particular movie watch it over and over again? if not, why not just rent it? all of my cousins have extensive dvd collections, but i don't want to ask them why. that might insult them. i'd rather ask here.
