The drama is binge worthy and re-watch quality. There are some slow moments but it is balanced with some utterly exciting climatic moments. Fight scenes were great; love the special power and all the special effects. The story is great to follow and the actors did a wonderful job. Although there was a moment where the extra fighters in the background stood lazily instead of putting a life and death effort; it was a laugh out loud joke. The ending is what you would expect, baiting, not disappointing, since there is a second season.
