I was pleasantly surprised.
I didn't rate Jason Mamoa at all before this but his performance in "See", although not brilliant, is quite good.
For those that feel the need to nit pick every detail that doesn't conform with their vision of a dystopian future then I give some advice - learn to suspend disbelief mainly because this is a TV show about a possible future many generations after a evolutionary change to humans.
It's a pretty good and entertaining guestimation from what I've seen so far.
