Jericho was only reasonably good, and no Firefly.
Actually, I didn't watch Jericho when it was on TV (I didn't have Showtime when it started, and didn't want to watch a second season without seeing the first when I got it later on).
I've been watching it via Roku over the last few weeks (three episodes left) and I think it's
as good as Firefly and B5.
