I also love the parallel worlds idea, and so watched the show regularly early on. The first episode absolutely blew me away and I couldn't believe something this enjoyable was really on the tube at the time. My favorites were Quinn and Arturo as well and though I watched off and on after John Rhys Davies left it was never the same, even though the initial story of the Maggie character was okay. I don't think I ever saw the last episode of this but I imagine not too much with the original characters was resolved?
