I only ever saw a little bit of Space 1999, but remember it as being complete pants...in fact 2000ad had a review when some of the episodes came out on video and said it was pants. However, it has its own gay fanclub*, which I don't think B7 has.
Tomorrow People sounds good. However, I'm skint. I think I'll go back to the library and borrow series 1 of B7 again
yours still open to nerdy suggestions
*really. I stumbled across it whilst looking for something else.
