Me, neither. I'm glad the script underwent some considerable changes if that was to be the original GB2. I think even if it had been made Murray would still dislike the film because it seems he has an instant dislike for sequels and he's known for being quite difficult and picky to work with.
I think fans would probably still dislike it as well and complain it was too different from the original, it was probably doomed no matter how it turned out. A common criticism of it is that it's too much like the original, but I think even if it'd been totally different it'd still be disliked because it's in the shadow of the original. A victim of "damned if you do, damned if you don't."
