Korean horror goes through the looking glass in this slick, stylish supernatural chiller. After a series of unexplained murders in a newly refurbished department store, head of security Woo (Ji-tae Yu) begins to suspect there's more going on than meets the eye. How come the CCTV monitors don't capture the killer? Why are all the corpses lying next to mirrors? And what do they have to do with the mysterious fire that previously gutted the building?
With a department store that's filled with more reflective glass than Dirk Diggler's bedroom providing a real sense of claustrophobia, Kim Seong-ho's eerie mystery thriller looks great. So great, in fact, that it's easy to forgive the silliness of the whole set-up and allow yourself to be swept along by the ominous atmosphere with its dollops of mirror mythology, corporate double-dealing and a hero with a dark past. Flawed but enjoyable.
