I haven't seen BSG, I tried to watch it once in the middle of the show but couldn't get into it. However, I saw Caprica Rebirth yesterday I felt a little lost, so I decided to watch the Pilot today and I must say I was pleasantly surprised. I think this is a promising show and the only side effect it had on me is that now I want to watch BSG as well.

But what I really liked is that I didn't have to be a hardcore BSG fan to understand what's going on in Caprica. From what I have read in the net, they were trying to reach the female population since BSG reached way more men, and at least in my case it worked.

However, I suggest that if you are trying to watch the show do it from the beginning starting with the Pilot.
