Great show to pick,I have seen all of the different incarnations.It was not just a space soap opera or shoot them up for sure.#1 First kiss(so it has been said) between a black woman and white man on a t.v. series.Social commentaryon "hippies" and the search for Eden.And those are just 2 that come to mind,so much of what was going on in the world was in those shows so why do I find nothing written here?
