First off, I was surprised by so many positive reviews here.
After watching first episode, I could not go any forward. I am a big sci-fi fan, more so when it involves humanity colonizing other planets. But the execution of this potential plot did not appeal to me.
Spoilers ahead
1) Androids: Androids look just like human, and move like human. Oh yeah, they can do much more with just programming. It did not seem believable for me that the advanced robot is trying to protect mankind.
2) Pace: Pace of the episode was uneven. Threw me off. There is no proper character development.
3) Special effects: Below par
