On Viki this drama is tagged as romance and fantasy, and it's not really either. From the little I knew about it going into it, I thought it would be an action sci-fi thriller, but it wasn't that at all. Then when I started it and wasn't getting the sci-fi thriller, I thought the romance would be strong. And while there is definitely romance, it wasn't as strong or impactful as I think it should've been.
Whenever the show did focus on the sci-fi elements, it was interesting and I wanted more of that, but the majority of the show is weirdly about the FL making her way through life and starting her career in hairdressing and makeup. The amount of time spent on the makeup drama was so strange to me. It just didn't fit in with the other world/messing with people's brains storyline.
Basically, this show took a really fascinating idea and told it in the most boring way possible. Okay, that's not really fair, because I did finish the whole thing and I didn't hate it. I just think that this could've been so much better if time had been spent on exploring the relationships between characters (Jiang Bo and his mother, Qi Lian and his father, Qi Lian and Jiang Xiao Yuan) and actually given us more of the hunt for answers (in a cinematic and exciting way instead of the slow plod that was shown. There really wasn't a moment where I thought the stakes were high and I was on the edge of my seat).
All of that said, I didn't hate it. I just wish it lived up to it's potential.
