People are saying the expensive part is the media, but how many movies do you really watch multiple times? If it is something I am going to watch once, I'll rent instead of buy. Only if I come across a movie that I can see watching a bunch of times would I buy it. I own Tombstone, Braveheart, The Matrix, and Wedding Crashers (might be forgetting something here), but I watch about 4 movies a month from rentals.
