Watching some old Buffy's and Angel's I was struck by how good Andy Hallett was as Lorne. I really think that the way to go would have been a sitcom with Alyson and Andy. As I have probably said before, they just didn't explore the comic possibilities of the whole jewish lesbian witch thing. Obviously Willow and Lorne should be flat-mates.
I think that San Francisco would be a good location for it, with Lorne as the chief barman at a club loosely based on the DNA lounge owned by a curmudgeonly software millionaire loosely based on jwz. With the occasional guest demon, obviously.
I don't see why there shouldn't have been a comedy spin-off from Buffy / Angel - after all the tone of the two was slightly different, and they took the opportunity for Cordelia to suddenly age ten years to Charisma's real age.
Anyway, another missed opportunity.
