TL:DR It's a good DRAMA movie, but it's not a thriller. Just a little note that I watched it raw and I am not a fluent Korean speaker, so I may be wrong on certain occasions. The things I loved: - Character portrayal. I loved how this movie took its time to show what the characters thought of each other using actions and glances rather than just words. I believe that it creates a certain tension of the viewer thinking whether the characters mean what they do, or whether it is simple over analyzation. This gives credit to the amazing casts and storyline. - The suspense. Yes I said that this is not a thriller, and I mean it, but there is some level of suspense (or tension) throughout the movie, and I credit the music for that. It's not your dramatic movie suspense but those everyday suspense that normal people feel because of human relations. The things I didn't quite like: - The trailer vs the movie. I came for a thriller movie and so I had certain expectations when I started watching. Therefore I am not going to lie. I was a bit disappointed when I watched it (but that added the element of surprise, which is always nice) Don't get me wrong though. I thoroughly enjoyed and was indulged in this movie. - The last scene of the movie. No spoilers, I know. But when you finish watching, tell me that if I am wrong when I say that the crew/director kind of miss the point of something and maybe thought we didn't notice something. Idk, might just have been me. Anyway, Choi Taejoon is in here and I love him, so this movie is borderline BOMB.
