I Saw the Devil (2010)

Both are about a cop who chases a psychopathic serial killer just after seeing someone they care about violently murdered.

benang merahnya sama-sama ingin balas dendam, namun storyline oldboy lebih dinamis kalau menurutku. gelombang emosinya lebih terasa, apalagi kalau sudah sampai di penghujung film yang dibuat plottwist. tapi untuk tingkat gore-nya masih juara i saw the devil sie

About how far someone can lose themselves in the process of seeking revenge.

Both are about serial killer
(Though "through the darkness" handles many other cases too n is not just about one serial killer)

Both are very interesting n grippng to watch.

(I saw the devil has unacceptable levels of gore Violence, so Be aware of that)

One man stood up for justice. One man facing the evil. Greedy politician vs psycho killer. Hardworking poor people suffering, pain, harassment. Gang, revenge, fight for life, fight for love, fight to relief the inner pain

Both are about men who turn into "monsters" trying to get revenge after seeing someone they know being violently murdered.

Both has a plot of a SERIAL KILLER

(Though "Beyond evil" handles multiple murders and serial killer is a subplot whereas in the other, it's the main plot)

Both are very interesting n grippng to watch.

Both are about a SERIAL KILLER
Lot of chasing n hunting

Both are very interesting n grippng to watch.
U will be tired n exhausted mentally, watching them running n chasing desparately, haha.

Both very violent movies where the lead is trying to pursue their own way of justice. Save the Green Planet has some dark comedy elements.

Other works of actor Choi Min Shik

He did a terrific performance in both.

Though the genres are different.

Both movie involve revenge. Strong main lead. Lots of brutality. To find the hard truth. Strategy and plot to get to the bottom of the ugly truth

Zhang Jing Yi is the FL in both. The chemistry is natural. The relationship had depth. However, BEITD does not have a satisfactory ending.

Both are Revenge themed movies in which the main lead takes it upon themselves to hunt down the murderer after a loved one dies.

both films are bloody revenge thrillers with harsh and horrific scenes.

In I saw the Devil a man is getting revenge from the serial killer who killed his wife and unborn child. In The Five a lady gets revenge from the serial killer who killed her family. Very similar plot but with different ways of getting the bad guy.
