I found this terrific little show about 4 years ago on cable TV and have never forgotten it. I would race home from work every afternoon just to catch it, and was really disappointed to find that so few episodes had been made. Yes it was far-fetched, but what SciFi isn't? Yes it was lightweight, but what's wrong with that? Not every show needs to be Law and Order Yes it required some concentration, but only a little. I don't care if the effects were good or bad, I enjoyed this show because the acting was good, I liked the relationship between the leads, and I've never been able to resist the dejavu of characters witnessing their own previous actions.
