Silent J’s review published on Letterboxd :
At what point does justice become vengeance? When does vengeance become something more sadistic? At what point does vengeance go too far? Those questions and others are brought up in I Saw The Devil.
This film is violent, bloody, haunting, thought provoking, and even outstanding. Lee Byung-hung is very believable and compelling. Choi Min-sik gives the most realistic depiction of a serial killer psychopath that I've seen in a long time. These two have amazing chemistry. Kim Jee-woon does a fantastic job directing and creates simple but very effective shots. The story is magnificent. The twists add smooth tension. My only problem is that it was too long too me and a few scenes could have been cut. The violent moments are enought to churn anyones stomach so approach with caution.
This film is unsettling, uncompromising, and unforgettable.
