I really wanted to give this show a good review. I honestly had enjoyed it up to about Episode 12, and did not understand why it got so many bad reviews here. Past that point, nothing made sense anymore and I was left very unsatisfied with the ending.

Would I recommend it? Sure, it starts off great, but be prepared for a terrible ending.

I think there was so much potential in the story. I was hooked on each episode in the beginning as the plot slowly began to unfold, but towards the middle characters started to act irrationally and couldn't understand what was right in front of their noses. I held onto the conviction that the plot would be fleshed out to a somewhat satisfactory ending, but it reached a climax somewhere halfway through and began going around in circles and circles for a few episodes.

Still, I think the production value is amazing. It's not easy to film and direct a time travel show, and I really appreciate the production team's and actors' efforts in seamlessly connecting each setting.

This is a drama that you'd want to binge in a weekend, but don't anticipate too much what is going to happen. Don't take it too seriously and don't get hooked on the supporting cast, because, unfortunately, they don't have very satisfying endings (particularly Doyeon... feel so sad for that girl). Anyway, just enjoy it for the thriller it is and don't think too much into it.
