We are working our way through it now. The first season is absolute trash that is so dull and slow that it's almost impossible to watch. After that things pick up and start getting good. I'm told that you can skip the first season and come back and watch it later with an understanding of everything it's setting up. But I decided to watch the first season in proper order.
Can’t be as bad as Earth: Final Conflict - I’ve watched the first season-and-a-half and was sustained at first by plot and then by awe at how shark jumpy it got after Boone died and how alien space baby rapid aged into an adult man and replaced him as the main character.
