Serenity's out tomorrow, so I'll get it Wednesday. I still haven't seen it, and I'm very much looking forward to watching how Firefly ends.
I've never really been one for renting movies, no matter how much more financial sense it may make. I guess if I watch a movie twice, that's maybe ten bucks or so worth of rental, and four to eight more to just buy the movie. Owning movies allows me to watch a movie I've seen before a second or third or tenth time precisely when I feel like it, which is nice. A rental would either need to be planned out in advance and sent to me, or be picked up from a video store. I may still decide to rent a bunch of movies for a while someday, movies that I don't think that I'll really feel like watching a second time. Movies like Casablanca and Lawrence of Arabia and The Shining, movies that I should see just because of the world I live in, not because I think I'll feel like adding them to my permanent collection.
I think I'd be much more likely to rent if there were a large library of movies available to me on demand without having to go somewhere or order anything.
