I hate calling myself a hypocrite, but I am. I said way back in this thread that SMG SHOULDN'T appear AT ALL this season, but changed my tune once I learned it was the last season. In th long run, it wouldn't matter if she showed up or not, because this show isn't about her. It's about Angel and his gang. I would love to see some other Buffy cast appear, but as for Buffy, wait for an Angel or Buffy movie.
As for commentary tracks, I think they should do what Stargate SG-1 has done on at least the last two season sets- have a commentary track, with production people, directors, cast, or a combination of the three, on EACH EPISODE. Along with a bonus featurette for each ep like SG1 season 6 had. THAT would make my day.
And is it me, or does the overall opinion of SMG change daily from "a nice person" to "a stuck-up bitch"?
