You might think i'm crazy as in "why would you recommend this movie to this movie" , some will understand, some will not: these 2 movies have a lot of similarities like you can even imagine the teacher killer in "Lesson of the evil" as a monster because of his merciless and unique behaviour like the actual "monster" in "Project Wolf Hunting". These 2 "monsters" are unpredictable and unstoppable, the only way to survive is either to hide or being bold enough to confront them.
I literally could not predict anything about what was going to happen! This is one impressive and unique thriller that I wont forget.

This movie was so damn scary, violent, gory and frustrating, I still liked it because of the "monster" whom annihilates everyone on his way. Not saying "Connect" has similar plot, but the friend of Irang made me think of this movie: they're both merciless when killing villains.

I'm surprised no one recommended this yet. This has so many similarities with "All of us are dead" and are both great watch and keep you at the edge of your seat if you're into this genre.

Both are demi-humans and have inhuman abilities and strength, both are also great to watch. I recommend part 2 of the witch too.

This movie gives very similar vibes compared to this drama, both characters give their huge bag of money to poor people, expect it was intentional for 1 character. This huge amount of money will of course lead to both deaths because that money is stolen. oops i spoiled a bit my bad :/

The plots are similar: the bag of money found by an innocent citizen is from a gang/criminal organization, the money cant be used because everyone involved will try to take that money back.

Both main characters kill villains mercilessly, but the witch is science-fiction based and a more structured plot.

In both movies they have supernatural powers such as extreme force, wound immunity, etc...
The main leads were both manipulated by evil scientificists.

The people in Sweet Home are infected because they're cursed but they would also attack innocent people like in this movie but they're not zombies, they can take any imaginable form of monsters.

The people are infected based on their strong desire, but in this movie the virus spreads faster by sexual act.

The cursed are seeing people as hallucinations like their dead family's members as in Dark Hole
. But in Dark Hole its a mysterious gas coming from a huge hole in a forest.
