I can think of several reasons why the studio wouldnt' want to release Buffy
The fans would, of course, have loved it if it was added, say to the newer slimline versions of season 1, as the Buffy
DVD extras suck, at least in Region 2. There's only so many times I can watch that Hepburn video.
I've never ever seen the introductory/pilot bit that was filmed for Angel
, I've heard lots of the footage was used for City Of
but I'd love to see it as made originally.
