Really wish there was a spin off don't think that there will be now :(
I read somewhere (can't remember where) that if they had done one then it would have been about Spike's life before he went to sunnydale. I think it sould have been set after Angel with Spike going to find and help Buffy.

Can't spike do his own battle fighting and bring in some other scoobies like weasley and xander and andrew or something

Maybe... The hellmouth could somehow, reform in a different place? And Spike, and Willow, and Xander have to go and keep the evil at bay? Just a thought.

I would have loved a Spike spinoff... but i think it should be about his life before sunnydale... that way we get more feed on his demented twisted mother.:)

@BuffyFan09:
Giles did say there was another one in Cleveland!
