Oh, don't get me wrong - there were definitely things to like about both S6 and S7 of Buffy; I just didn't think they were as good overall as the other seasons. Same for S4 Angel.

But I hold Firefly above either Buffy or Angel and maintianing such a high level of expectations would be a challenge, even for Joss.

Same goes, and I agree - but you know, with that cast and the magical awesomeness that made them so close and such a great ensemble, he might just have been able to pull it off.

If only we could have Firefly and Castle at the same time....
