I blogged about Star Wars first because it was my earliest foray into science fiction, and thus remains my favorite by default of seniority. It has its issues, but what film/series doesn't? It is wonderful for it's mythos, pioneering, and good ol comforting nostalgia.
Third on my list is easily the redux of BSG. I'm not Mormon, or at least not anymore, but having grown up surrounded by that particular religious culture I couldn't help but glean some of the beliefs. Some may know this, some may not, but the Mormon mythology played very heavily on the writing of Battlestar Galactica.
I never saw the original Battlestar Galatica, which lasted for one season in 1978, but I loved loved loved the remake that ran multiple seasons 2004-2009. When I first watched the pilot episodes to the remake I was quite lost. Thus I began at the beginning, with the prequel Caprica. I was instantly hooked with the characters, happenings, and over all establishment of the story. Sadly it was dropped after only 1 season.
All told, both Caprica and BSG were fantastic shows and I cannot recommend them enough. I have had discussions with other fans regarding the preference of the original versus the remake and people seem to like Edward James Olmos as Adama, whether or not they favor him over Lorne Greene I haven't heard. I think it's cool that Richard Hatch was in both. The one complaint that has been voiced many times is that Starbuck was a girl in the remake. I say it works anyway, besides...she's not very girlie.
Anyway, enough of the rambling here's some ships to ogle
