This drama had so much potential. The plot was good at first, but then it went downhill. The special effects are amazing and the concept is good but the story isn’t - which is why I was really disappointed with this drama. It got confusing and the plot kind of went crazy halfway through. I watched it because it was supposed to be amazing and everyone has their own opinions... but it’s not that good. The only good things were the special effects and the acting. Again, I’m disappointed with the plot in this drama and I wouldn’t recommend watching it.
