Such a good premise. It could have been so much better. This was truly a missed opportunity that could have resulted in an epic show. I think part of the blame lies with the direction and the VFX. The male actors were good but the lead actress gave a very plastic performance. I was fed up of watching her and I have to admit I thought about other people who could have played the role a lot while watching her onscreen. In the end, I really wanted to know the story but watching the remaining 12 episodes seemed too onerous. So, I stopped wasting my time and read episode recaps of the show. I don't regret it. I watched snippets of the last 12 episodes(skipped through them) and the ending.

Overall, I have rated this 8/10 solely for the story and Son O Gong(the coolness factor is strong). Do watch it if the summary interests you. Every viewer is different and just because I couldn't complete the series doesn't mean others can't enjoy it. Maybe I'll watch the rest of it someday.
