I've got very mixed feelings about this - like a lot of you, I guess.
On the one hand, there's enough going on to keep me watching, but on the other, it's ludicrous that it needs 10 episodes to tell the story. There's not a tale ever written that needed 10 hours to tell. When Children of Earth came along, I had my doubts beforehand, but the 5-episode format was, in retrospect, bang on for what the creators of the show were trying to do.
I'm certain that the same could have been done this time, but if the tie-in between the 2 production companies really demanded 10 episodes, would it have been too testing to do more than one story?
Oh, heck - TBH, this series could have been a disaster, given its gestation, but it's far from being that. I'll keep tunig in, but the big reveal had better be good!
