Everybody else seems to either love the series or hate it, passionately either way. Personally, I simply find it mildly interesting, better than a lot of what I've seen, but by no means spectacular. It is, of course, loosely (the operative word) based on the early history of Seattle, and on various projects (including, but not limited to the best known group, the "Mercer Girls") that enticed young, unmarried (or widowed) women to Seattle, to marry the settlers.
One interesting bit of trivia (and a probable reason why the series was as good as it was): several of the regular cast members had made guest appearances on Star Trek, some years earlier. Mark Lenard (Aaron Stempel) had played both Sarek and the first Romulan Commander; David Soul had appeared in "The Apple"; Robert Brown had played Lazarus in "The Alternative Factor."
