If they had stopped after the first season, this would have been a well-deserved 10, but the second season was at best a minus 3, and season three - well, I could barely pay attention at that point, so just call it a zero.

The initial concept was such a brilliant send-up of every sci-fi, time travel, and movie cliche that you could be entertained simply keeping track of the allusions and references, and if the story line was derivative, well, that was sort of the point.

It also felt like the actors were having fun with their roles and the writers were coming up with some character development in a variety of situations.

After the first season, though, all that went by the wayside, with writers and actors just going through the motions.
