Query: What a waste of talent

This is a beautifully-shot, intensely-acted film that, unfortunately, has no intrinsic merit. Long and nasty, it is disease on film, no matter how accomplished the film making. I feel diminished in my soul for having watched this. Kim soo-huan's hunt for the killer in the beginning of the film was excellent. The rest was a waste. Referred to as a revenge/horror movie, the true horror is that the over-the-top violence becomes, ultimately, tedious.
