I liked Blake's 7 better, too, but in a weird way it stuck with me less. I'm not sure quite whey except that I know people for whom it's huge and I don't feel I have as much right to it. Which is weird, but me.
I'm no sure about fantasy: it used to be wider and there are still more books in which are front and centre == but it carries all the social baggage which is wearing in itself. And there are too many damsels.
