I've currently watched 10 episodes and to me it is a worth drama to watch.The story is well written and the acting is very good. Though others might not like the CGI used in the drama, but to me I loved the CGI because I am starting to get bored with those floating around in dramas.
Anyway am not commanding anyone to watch it. I just think you should not just read the reviews and comments give it a chance watch at least 6 episodes and see if it's to your liking and make your own judgement. Otherwise you might just miss out on a good drama?
