... terrible. There are too many plot lines to be able to get even minimally invested in one.
The main plot line, the mission of the ship, and the difficulties of said mission with one main antagonist causing the mysterious goings on aboard the ship would have been plenty.
Yet they had to have half a dozen subplots diluting the storyline. They weren't even interesting character building plots. Half of these plots barely made any sense, never got a resolution, and were poorly concieved from the jump.
The fact is that this show got made solely on the back of Martin's name and without that name recognition guaranteeing viewership while GOT fans eagerly await that show's final season no one would have put this on TV.
Mr. Martin, please get back to doing what you're good at and release another book already, ffs.
