If you have seen Michael's Haneke "Cache" you will first regard this as Korean rip-off. There's adopted brother, injustice and a some unpleasant mystery in the air. First part was quite entertaining but as soon as I found elements common to both movies it kind of spoiled the whole surprise. Do not worry though. Actually, this one focuses more on the thriller angle and gives totally different solution: slasher violence included and deep insight into upper middle class life omitted.

Anyway it has a lot of thrill and may be entertaining. Provided you know (and now you do) that this is not Asian "Cache".
