Oh, you haven't seen Firefly... I see.
Probably not a Joss Whedon fan either? His style isn't for everyone, but Firefly is his best offering yet in my opinion, and will always be a favourite. The melding of east and west into a quirky space opera was pure genious. He also managed to tame his goofy humour without removing it entirely. Oh, and the companion is hot and I have a thing for River... So there's that too.
I love Dead Like Me, and just bought season 2 and have been watching it, so it is fresh in my mind.
Nate - I hear you on heroes, and I agree that they made some mistakes. That said, I LOVE some of the characters and even taking what they are doing wrong into account... They are doing a lot right.
Looks like I'll have to check out deadwood though. Just what I need, another show to watch.
