Read good things and saw it got picked up for S2. Binged the first 4 eps on Sun and came away pretty impressed. The universe they are working with felt too big at first but it all makes sense now--except maybe who the 4th party is that wants war?
I got the 4 parties but they are giving an impression/hint that there is an alien component. I really want to go read the books but I know they would do the same as Game of Thrones and eventually deviate from the story.
The factions so far are:
Earth
Mars
Ceres
Mormon Church and/or the builder of the ship
