*Contains spoiler* This movie was so frustrating. The girl was deaf and mute so by this age she should know that not many people know sign language and that she should communicate by writing. Like in the market scene she should have asked for someone's phone to write. She should have gone to a store and asked for help instead of asking for help from strangers. And she was telling the killer her dreams as if he would understand and let her go. And when the paramedics arrived the guy should have told them to call the police as the killer was chasing the girl but instead he went after them and when the 3 were alone and he got his sister's location he should have called the police and saved the girl but instead he left her alone. And when the mother saw the phone she should have told the police officer, I know he threatened her but you are at a police station what can happen there? And the girl kept making noise and swinging the knife instead she should have stabbed him. And the guy he kept turning his back to the killer giving him chance to attack. The characters were so stupid. It was nice but so frustrating.
