It was one of the anticipated movie in my watch list but it's just such a mess.
It just left me questioning the whole situation.
1. Why are deaf people walking at 10 pm alone in the streets ? Isn't it dangerous?
2. The mother could have just made a noise or hinted out the things in his bag and it would have been done and dusted but no
she cannot even do that in a POLICE STATION.
3. There are literally no police officers in police station so anybody can fight over there. Even when mother and her deaf daughter inform them then they are not even reacting to that?? What king of police officers are they?
4. Do you want to be alone at home when you know that murderer is trying to kill you? She could have gone with her mother.
And the most stupid thing at that dangerous situation is to forget to lock the door. Seriously?
5. She can't really sense a person behind her really, you want us to buy that?
6. The brother character could have easily made a phone call to police while searching for his sister but no just leaves the deaf girl.
7. Most stupid thing is SHE IS SCARED AND BLEEDING. No matter what at least even one person would be suspicious of her condition and try to help her. Though this movie wanted to potray the way we treat handicapped people but this is far too fetched. Even army people just present her to him.
8. Lastly, when deaf girl was saying she wants to live more in sign language. Do you think serial killer will whole heartly understand that? As a viewer if there were not subtitles then couldn't have understood anything so how can he.

One positive I found is Wi Ha-joon's ( serial killer) acting other than nothing is good. Just wasted my time.
