I don't understand why there were a lot of bad comments. This show had a lot of potential.

Story: I could understand on one part of why they were saying that it was confusing. The first episode was meant to be confusing because of how it focused in and out on how it came about when Mi Ran and Dong Chan went into the cryogenic capsule. The show didn't drag on and stall on the mystery when clues came up like some shows do.

Acting: The acting was great! I was honestly hooked on the first episode when i watched the actors and actresses get so in depth of their character. they made it seem as if their character was a real person. What made this more interesting is that there was a couple actors that were from another one of my favorite k-drama called Strong woman Kim Bong-Soon as soon as i saw them. I instantly knew that this show would be unforgettable.

Music: I honestly can't say anything about the music because I didn't pay a lot of attention to it. I was so engrossed with the acting and the story

Re-watch Value: As you can see the re-watch value is really high. I will most defiantly be re-watching this show.

( note: at the very beginning i was really hesitant on watching this show over what it was about and because of the comments below. But i wanted to draw my own opinion and watch small clips of this show on YouTube, finally deciding to watch it, and boy this show is actually worth defending over. )
