I watched the remake of Battlestar Galactica over the weekend (pilot film), and am now working my way through the series. I was impressed; much more coherent and dramatic than I was expecting, with a lot of nice touches. Clearly a great deal of post-9/11 sensibilities being worked through, but I am intrigued to see where they go with the cylon/human interactions, especially Boomer and similar characters. It doesn't look like being a simplistic good vs evil story, which is refreshing.
Haven't managed to watch Serenity yet - maybe this week, assuming that it's still on show somewhere.
