I think the weakest non-spinoff series was Tomorrow Stories. I liked the earlier Tom Strong stuff better, but I'm still enjoying the current arc. It's not Moore's strongest work, but I think it's better than most of the tripe that's out there now. It's fun. It doesn't take itself seriously. Very silver age-y. A soothing detour from the ultra grim n' gritty, so called "realistic" books that fill the racks today. There should be always be a place, even if only a small one, in comics for the escapist science fiction fan(the genre that gave rise to comic books in the first place).
