Well, it has some poly-themed storylines and features characters in "alternative" lifestyles, so I thought there might be some other fans of it here besides me.
I highly recommend picking up the original series which has been released and re-released in "graphic novel" format.
The "new" series and spin-offs are not quite as impressive to me - with the exception of "Birdland", an adult/pornographic mini-series released under EROS Graphic Albums (ISBN: 1-56097-200-9).
