Park Shin Yeh's acting was superb. It was my first time to watch her movie and she was great here. I felt the emotions the frustrations . Great performance. The plot is also superb. Masterpiece story and acting. I can't even watch it again because I got hurt so much in the scene where her father came back to her life then she lost him again. It was heartbreaking and Park nailed it.
The editing is also good. The special effects superb . It's a masterpiece movie.
