I don't know why a lot of people criticizing this drama.
For ad?! After reading their reviews only I got, what they're telling ad's that it's used here. And those are not really relevant in the story line.
First of all I get a Hollywood style vibe from this Drama. It was actually perfect in it's every aspect. Acting, OST, Story, Production and Plot. It was really a unique story so far.
The OST are really good and especially, Gravity (I'm using this one as my caller tune) and Maze.
In Acting aspect I've seen a lot of reviews criticizing Lee Min-ho I don't get this why?! He's perfect for his role as both wise and spoiled King. Hats off to those are performing double roles. I was wondering how they choose the cast?!! Bcz each and everyone got perfect role and they did their best.
It's a drama for those who loves
Fantasy/ Sci-fi (parallel universe)
Thriller/Mistery
Melo/Romance
Smart ML and FL
Happy Ending (Most satisfying one, we can get 4
couples at the end)
Plz don't get swayed by the negative reviews it's really a good Drama. I've watched it about 5 time's.
