Despite the rating the comments are very positive so I gave it a try. To be honest at episode 7 I was loosing interest and I wanted to drop the drama but it only has a 10 episodes so I finished watching it.

The concept of the story is good but it was not executed very well. Unfortunately nothing about this drama stands out for me. Also I don't like the open ending, specially if there is no sertency that there will be another season.

The acting is okay as their performance is average and I did not build any sympathy or feelings towards the characters.

I really liked the edvanced technology they showed but it is a shame the drama is lacking in so many ways.
