I missed the first 2 episodes, so I did not see what exactly happened to the moon. And I don't know how much background was given on what everyone was like before the 'three moons'. But I have seen the last three episodes, as well as scenes from prior episodes. I have enjoyed them. This is a nice change of pace if you have had enough of all the CSIs and Law and Orders on the air! It is nice to watch a show where something horrible is not going to happen to someone (or everyone!) all the time. It reminds me a little of Gilmore Girls and Northern Exposure. There is enough horrible stuff on the news all the time. We need some lighter entertainment - and this has given me some. Very good cast, and excellent guest stars.
