There are some things I appreciate about this movie because they were good. So I'll start with them. First of all, the actors did a really great job. But I did not expect anything else, because I know the possibilities of each of them. I really liked the transitions between scenes with and without sound. The scenes without sound showed the perspective of the deaf mother and daughter better, and I think it was a well-thought-out move. The last good thing is that the ending was satisfying enough.

Now let's get to the things I don't like about this movie. It was boring until the end when Kyung Mi confused the killer. It was basically a cat-and-mouse chase throughout the movie. With people around who couldn't recognize the situation.

Despite some good things, I'll probably soon forget about this movie. Obviously, a good general idea combined with not knowing how to develop it always results in a boring production.
