Query: Serenity

If you're a Serenity/Firefly fan, I'd recommend making the purchase. There are no new features, but the quality of the picture makes it work the price for me -- especially if you can get it on sale. This is one of my all-time favorite movies and I can watch it over and over. I love having it on Blu-ray and regular DVD so I can watch on any TV in the house.
