This movie's first half excited and fascinated me with it's chase scenes, the serial killer manipulating everyone and the abduction of Kim hye yoon's character. I loved the family part of this movie, especially the mother-daughter relationship. But the last half was extremely disappointing to me. The serial killer's actions were impulsive, but the police were oblivious to them. The police's potrayal, to the very end, was very badly done. For most of the parts in the last half, they showed some chase scenes and some action scenes between the serial killer and the female lead.

The casting was perfect and everyone in their character did an awesome job, especially, Jin ki joo and Wi ha joon. Even though Wi ha joon's character's only job was to swear, hit people, manipulate everyone and getting away after doing some very impulsive actions that explicts shows that he is the serial killer. Honestly, I feel that the latter half could have been better if they didn't try to stretch the movie by showing a lot of unnecessary chase scenes and very predictable plots.

I didn't even notice that the movie had any music because I was just staring at the movie for the sake of finishing it. I really expected something better after watching the trailer and the teasers. I thought it was going to be an intense mystery and a psychological battle between the female lead and a serial killer as there aren't many K-movies that shows something like a mental fight with a female lead. But what happened was that they revealed the serial killer to everyone too soon. They should have gone for some more manipulation from Wi ha joon's character, instead of those impulsive actions. It would have created a fear in the viewer's heart(?).

I am not someone who like action scenes in thriller or mystery movies. So, it might not be for me. But if you are someone who likes action scenes and mystery, then it might be a good movie for you. I would recommend it. But the story didn't seem that interesting to me.
