This is the honest review. The drama is thrilling. Also the vfx is good. I usually watch 3 or 4 episodes a day. But i only able to watch 1 episode per day due to the lag. Some episodes are good. Some are very lagging. If you like thrilling and little fantasy is this the drama for you.The way the seris going is not really enjoyable but good. For me i don't like the climax. I suggest you watch it if you have time. One time watchable.
In my opinion you can watch Many other drama which is better that this like happiness, all of us are dead, my name.
