I bought/watched the movie Serenity a few times, always thinking I was missing something, not knowing what it was, then a Google search revealed Firefly. I first rented it, then bought it on DVD. Later it became available on blu-ray and I bought that one also. I think I paid around $50 for it from Amazon at the time. It's one of my favorite TV Sci-Fi shows. It's a shame there was only one season. Made by Joss Whedon, who also made Buffy the Vampire Slayer, and Dollhouse, plus other stuff.
