Nobody actually cares about this sort of thing. Caprica failed in large part because it was a muddled mess, not for whatever connections it had or failed to have with its parent series.
Yea, Caprica's problem was they threw out too many arc elements from the beginning, and and tried to advance each one a little each week, so, it seemed to most, that the arc wasn't moving, and didn't know where it wanted to go. If they had stripped it back to 2 or 3 (or even 4) Arc elements to start with, and play them out, and then layered on top of that with more, I believe it would've been much more likely to succeed. I personally didn't mind, I'm fine with a slow burn (I love Babylon 5 Season 1, which many can't get through, their first time through, until they learn what's coming, and can identify what is actually moving), but, yea, to succeed, they needed to better plan their world/Arc building. If you're able to accept that first half season, though, I think it really becomes a great Series by the end, and I was sad to see end (Though the CODA really helps make it a complete Series)
