This is not a pretty story, this will let your heart sink. This movie amazed me, the trailer looked good and the movie delivered it! The story isn't unique but they worked it out greatly. It kept my attention from start untill finish and I was blown away. Every minute in this movie will make your heart sink deeper. The acting was amazing, the mother (kim hye soo) delivered it and acted top notch! She convinced me and did a splendid job. Also the rest of the cast were brilliant. The music was perfect and fitted every scene. I would rewatch this movie with friends, I really enjoyed it Watch this if you like action, a good storyline and great acting. Skip this if you want romance and don't like blood.
