Maybe I was bored, so I finished season 1 with a 5/10 rating. Rated seasons 2&3 6 over 10. I started getting hooked on the show, because the plots and the effects seriously changed in season 4 and my rating jumped to 7. But seasons 5 and 6 definetly proved this show is among the best Sifi series. Astonishing production, visual effects, and very futuristic plots. I had to give season 6 a rating of 8.5, but since no halves on IMDB it deserves 9/10.
