Interesting observation, from this thread and others - people who watched the show as it aired dislike the last season far more strongly than people who got into the show on DVD. I’ve noticed this phenomenon for other shows as well, but it seems especially pronounced for BSG.
Spoilers below:
[spoiler]My working theory is that folks who watched the show week to week got a lot more emotionally invested in the minutiae of the plot and the various mysteries, and thus were correspondingly more angry and bitter about things they disliked in how the show ended. It’s “Lost” Syndrome - when one spends a long period of time poring over clues and theorizing about how they come together, it’s natural for one to be more disappointed when the revealed conclusion isn’t quite as satisfying as one had expected.
In addition, BSG’s live viewers were originally sold on the show as the closest thing to “hard sci fi” on television, a technologically plausible series that also served as a refreshingly breakaway from space fantasies like “Star Wars” or the (then seen as) naively optimistic politics of “Star Trek.” The first season and a half of the show, in particular, focuses less on the big picture Plan than on episodic sociopolitical allegory. So when BSG itself moved more towards fantasy (although these elements were present, to some extent, from the beginning), many longtime fans viewed it as a betrayal of the show’s core ideas.
But newcomers to the show watching it on DVD won’t have that background. They may have heard that BSG is harder sci-fi than your average space opera, and they almost certainly are aware of its uncompromising nature when dealing with the politics of war and terror, but they’ve also probably heard something about the mysticism of the show. More importantly, they haven’t had 2+ years to get used to the show as being one thing and then becoming another.
To them, the show starts as a gritty political thriller with fantastic qualities, and smoothly transitions over time into a space fantasy series with gritty political elements. And importantly, that transition only takes place over a few months (or however long it takes to watch the show), rather than the five years it took those of us who watched the show live. They tend to more strongly remember the high points and pretty quickly forget the low points, since it all kind of blurs together anyway.
IOW, those of us who had to wait a week just to sit through the shitstorm of “Black Market” remember it as a horrible debacle, while those who watched it on DVD remember it only as an annoying, hourlong distraction between “Epiphanies” and “Scar.”[/spoiler]
