I actually haven't seen the original movie, but I'm against in principle because it wasn't what Joss wanted, and I'm interested in your insight about it (also, I don't know if I've mentioned it, but it's beyond awesome that you did your dissertation on this).

no one particularly minded because we could ignore it completely Exactly. Up till this point, they were irrelevant, but if they actually go through with this, they will have all of fandom after this.

You're so right about the comics--with, say, Bond or Batman or Stark Trek, those franchises have been around for decades. Buffy is still new. Why on earth would you want to "reboot" it?
