I think there was a better balance of drama and action in those shows. It wasn't the lack of action that bothered me, it was the lack of science, or more specifically, the lack of the moon. There are plenty of great dramas out there, but in this show, whenever we weren't in space, I found myself counting the seconds until we were again. The drama back on Earth just isn't that compelling. The subplot about the adopted daughter discovering herself and her real parents being a standout example. It felt completely unnecessary. Just shoehorned in there for no good reason. This is a TV show about an alternative history where we colonize the solar system. At least stick the drama in space!
