I think this would've been better on Amazon or Netflix. The slow burn of the mystery works in the book and would work while binging, but, without spoiling anything I think everyone watching "knows" that Miller's plotline of civil unrest and the missing girl must have SOMETHING to do with Holden's plotline of mysterious bad guys blowing up ships on the reg... But halfway through the season what that connection is just as big a mystery to the audience as it is to the characters.
IMO, and I'll spoil this, instead of trying to draw that connection through Miller's hunch,
The time they spend on UN bickering and the Anderson flashbacks should've been spent cluing the audience into the actual plot.
