I started to watch this series on Netflix's free downloads, and I have to say that I haven't seen this kind of addictive story telling since Babylon 5. It starts out slow but when it picks up speed it does it with monumental force. The characters are likable and intriguing, the story additively intoxicating, and the experience very rewarding.
If you haven't seen this series yet, rent the season 1 dvd's and go for a joy ride that has been absent from television since the end of Babylon 5.
