Bronies 4 Life, yo.
Battlestar Galactica: This was a show that I had been introduced to when it was at its popularity peak, and it's easy enough to understand why it was popular. The show explored a lot of relevant themes and had a fairly hard-science approach to science fiction, which was appreciated. The characters were generally solid and the show was pretty good at making sucker-punch drama moments feel appropriate, which is more than I can say for just about any show that uses sucker-punch drama moments.
At any rate, I watched much of the show as it was coming out, but I left for Japan in the middle of the final season during the writers' strike. So I had never gotten around to seeing what happened in the last 10 or so episodes. I was probably subconsciously worried that the conclusion wouldn't live up the grandiose plot and character development the series was known for up to this point. And really, those fears weren't unfounded - as a member of the fanbase, my exposure to all of the Wild Mass Guessing had pretty much played out all of the possible conclusions for the series so any hope of 'surprise' was lost. I felt the ending was... fitting. It was certainly the type of ending I was hoping for, but it didn't really feel very moving or 'complete' when it was all done.
The overtly religious "God is Real, Skeptics be doomed" message was a bit of a turn-off, too, for all that the series had been pushing it since the beginning. I was kind of hoping for a more real-life explanation in my relatively-hard-science-fiction, even if the series had been tackling issues of faith and God all along. I guess I would have been happier if it had been more ambiguous about the existance of God, and just kept the issue on 'faith'.
I will say that the use of flashbacks focusing on the characters' pasts that led them to ending up on the Galactica was a great touch and the most satisfying part of the finale episodes, so it wasn't all bad and I'm glad I watched the series all the way through.
