I'm currently watching the third season, and considering that other shows lose their steam long before that, I'd say that this is a success. Good performances by the main and secondary cast, an interesting premise with well developed stories, and good special effects keep me engaged (minor gripe - they seem to have artificial gravity, but only when inside the moon base!) Some of the side detailes are quite funny - the show mentions Bill Clinton but it seems that in the alternate timeline he stands no chance of being elected. Also Margaret Thatcher did not survive the real-life attempt at her life, while John Lennon is still alive (and the Beatles were reunited!) and so on.
