See, now, I hadn't watched broadcast TV since Babylon 5
ended (couldn't afford cable anymore), but I'd been a big Buffy
fan prior to that, so I was only vaguely aware that Joss had a new show in 2002; I think I heard a commercial for it on the radio.
When the first trailer for Serenity
went online in April 2005, it spurred some recognition, so I went looking for the Firefly
DVD, and then watched all the episodes in two days!
Oddly enough, I consider it to have the best Pilot episode that I've seen, and I've watched that one about 7 times now. I appear to be alone in that.
