BSG is the only television I watch. The rest is a wasteland, except perhaps Discovery and History Channels. I'd likely cancel cable but for BSG.
In my opinion BSG is as ground-breaking SF as Babylon 5 was in the 90s. Perfect? No. Lots of new takes, and insights into humanity? Yup.
There are a lot of loose ends, though. I wonder how they're going to clean them all up.
