I remember watching a trailer for this a few months ago and thinking the serial killer was the aggressor the entire movie. I was wrong.

Anger is an addiction. When someone gets mad, they want to stay mad, even when they tire of it and destroy the lives of others. This can be as small as a petty friend drama, or as large as a full-scale revenge plot. The rampage is unable to be stopped until the person is, at least before wrath consumes them whole.

If you take anything away from 2010’s I Saw The Devil, that may be the smallest and least sensitive reading you could possibly get. Focusing on an intelligence agent’s quest to hunt down the serial killer that murdered his wife, both parties end up in a cat-and-mouse game that affects everyone around them.

The most talked about aspect of the film is its gratuitous violence. This film never lets up its attack, nearly desensitizing the audience until the very final shot, falling into the same vein as other Korean revenge films like Oldboy and Mother. Clocking in at over 140 minutes, it is an endurance test to get through certain scenes involving torture, mutilation, and murder in between lengthy bits centering around character disposition. Some call it torture porn, graphic and tiring; not to sound like the edgelord in the room, but that could be the point. In one’s conquest to exact revenge, you will eventually find the journey for such satisfaction tedious and uninspiring. You may forget what you were even fighting for. Does that mean it’s worth it to go on? I Saw The Devil doesn’t make a particularly compelling argument, showing both parties devolving into insanity and unsavory sadism in a world where there is no good or evil, just wrath, envy, lust, and all of the other sins. 

This point seems to go over many heads amidst the rampant violence against women and lagging pace, not that I don’t disagree; I have yet to see the rest of Kim Jee-woon’s filmography, but many online are quick to point out very few of his films have a favorable view of women. From this one film, it’s important to note the only female characters are shown as helpless, either mourning the death of Kim Soo-hyeon’s wife, Joo-Yeon, or becoming a victim of sexual assault. It fits the killer’s motif, yes, but it’s tiring and even degrading. It makes you wonder what could have been done differently, given the fascinating take on revenge.

I Saw The Devil’s strongest aspect is its visuals. The opening sequence with Joo-Yeon is one of the best cold openings I’ve seen in a long time; the second you see the glimmer in the “Good Samaritan’s” otherwise black eyes, you know what you’re in for: something creepy and unforgiving. Its immaculate cinematography is complemented by a sickly color palette that is simultaneously pale, harsh, and dark. Pretend all the violence was off-screen; you would still walk away feeling nauseous.

Additionally, the performances by the two leads, Lee Byung-hun and Choi Min-sik are mesmerizing, perfectly capturing two psychopaths in a sick loop, hell bent on destroying each other. I see that the former is involved in Squid Game and KPop Demon Hunters – not the plot twist I expected to see after I watched him make the world’s worst Rube Goldberg contraption. Despite both their sorrows and pains, neither express any regret of continuing their little game. And that may be the biggest tragedy of all.

I strongly recommend this to anyone who has seen Oldboy, Lady Vengeance, and Mother, yet somehow not seen this. And if you have not seen any of those titles, this isn’t a bad place to start – just be warned: it’s an intense, polarizing ride that leaves you sick to your stomach.
