Query: 4 seasons later and still hooked.

I've been watching this series since the beginning. Yes, it has had some rough spots on occasion, but since season three and going into season four, have really enjoyed the series. Even at this point, not quite sure where the overall story arc is going, which is a good thing. I remain both engaged and look forward to future episodes. Now the tough call, as to which universe I find more engaging. At this point, I'm leaning toward Fauxlivia's. It's just a bit more edgy.
