I finished it tonight, saw the finale. I must say I was very disappointed.
The visuals were well done, the actors were credible, but I felt the story line was not believable, nor internally consistent. It was like a group of people were asked to write a novel, and a different person wrote each chapter without reading the other chapters, nor discussing with the other authors.
It just didn't seem internally consistent at all. But I tend to favor "hard" science fiction, and this was certainly not hard science fiction, but a kind of futuristic fantasy to me.
I was really looking forward to this series, and I almost feel like I wasted my time.
I won't say more because I would begin to write spoilers for those who aren't finished yet.
But big snakes? Really? That fly? Come on!
