I just got back from the Alamo, where they showed Hush and Once More With Feeling, the Buffy Musical. One of the best TV episodes ever, let alone one of the best Buffy episodes, Hush showed critics that Buffy the Vampire Slayer was more than just some pointless high-school banter. They made an episode where about 50% of the show had no dialogue whatsoever. It was brilliant. The writers had a real knack for story-telling, something that is often missing from drivel such as Friends. OMWF was of course spectacular in it's own right.
With Buffy and Angel reaching their conclusion, Firefly was supposed to pick up the torch. Unfortunately, it was quickly axed after Fox execs basically ruined the show. They didn't show the original 2 hour opener, in favor of what was probably the worst episode in season one. I imagine that quite a few vieweres were turned off by Train Job and never came back to the space western. I guess now we have to wait for Firefly's return as Serenity.
