(THIS REVIEW WILL CONTAIN SPOILERS) The movie was thrilling from beginning to end... I was shocked by how good the movie was. Each actor gave life to their character. Jin Ki-Joo (who played the deaf girl, Kim- Kyung-mi) did excellent in expressing sign language and being fearless when confronting the killer. Wi Ha-Joon (who played the killer, Do-sik) gave chills down my spine and perfected the killer role. Kim- Kyung-mi was very smart in realizing that her mom doesn't have perfect spelling which saved her from opening the door(in the house scene) and putting the knife in Do-isk's hand to frame him of stabbing her( in the last scene). The brother and sister(Seo-Jung & Jang-to) did a fabulous job portraying a concerned sibling and stubborn sibling. The mom also showed how much she cared for her daughter which was delivered nicely. I overall am pleased with the movie and it's personally one of my favorites. 😊😊😊
