I love sci-fi and can follow anything you throw at me and I also love k dramas so I was excited when there was a real sci-fi action k drama. I finished the final episode and I can’t believe after 16+ hours they couldn’t seem to figure out how to explain anything. They just throw random things in the show with either no explanation or a pathetic unclear explanation that barely makes sense. I kept thinking they would maybe explain later in the show but they don’t. They wasted time and money trying to do pointless scenes of the girl fighting a hundred men for a bag of Doritos. This show had so much potential and the actors were the amazing but wow the director and/or writers seemed like they didn’t commit to a sold story line and had too much fun with special effects to bother with keeping up with their own twists and turns. I could go on all day about how it could have been better but this is the gist, kinda a frustrating waste of a show.
