This film begins by showing off its great technicality, the scene when a woman employee in a mall looks in the mirror in the restroom and then when she looks down to bring a falling item while her reflection in the mirror doesn't follow her movements it's very jawdropping, even though I know how they did it.

With that great opening in mind then few more kills involving mirrors, obviously I started expecting another some supernatural things related to mirrors, but what I get is detective mystery thing. It's not bad but it's like I'm being kept away from a crystal clear diamond that I could get. I'm disappointed.

For the ending, I don't really understand how it came out like that, made me confused with the concept of the mirror world.

Overall, enjoyable, the technicality impressed me but also at some point kinda dissapointing.
