I think the reason this show ended up falling flat for me, was perhaps due to the stellar reviews I read on MDL - which set my expectations very high. So if like me, you're coming into this thinking it's going to be a psychological thrill ride, like none you've ever seen before, it will probably end up disappointing you.

The first six episodes (so almost all of the show) are all very slow, and the character building feels un-organic and added on. I can not stress how slow this show moves, even in the more 'thriller' like scenes, the editing cuts down the pace.

I will say that the last two episodes, the last one especially, were the highlight of the show. Finally bringing some of the psychological thriller elements that I had been waiting for - especially the ending was a highlight for me.

Another issue I found, was that the characters weren't likable, especially the main character Moo Yul, who was like watching a wall act. I don't think the problem there was Baek Sung Hyun's performance, instead the character Moo Yul was just incredibly boring.

Some things I did like about the show: The story line/idea of it all, though it wasn't executed as well as it could have. The soundtrack was amazing and really fit the vibe of the show. The cast really did their best with the material especially Kim Sang Kyung. And the visuals were great as well.
