I really wanted to LOVE this movie. BUT…
This movie has a REALLY interesting plot. BUT the characters are the weakest part of the movie. While watching a movie we want to root for a character or at least understand them. In this movie we learn the history of both killers but still it lacks emotion. And for the daughter she doesn‘t have much influence on the film tbh. She‘s just there to create this thing between the killers. She has no character developments. From the start till the end she’s the naive daughter/damsel in distress. The acting is good. Sol Kyung Gu is AMAZING. Seolhyun isn’t a great actress but her acting in this movie was good and believable. Kim Nam Gil’s acting was also good. Another thing about this movie is that it has so many twists and at some points you don‘t try to connect the dots because you‘re lost, you just watch it. It becomes complicated and starts to lack sense. I don‘t think I‘ll remember what happened in this movie in a week.
