Midnight (2021)

Both are thrillers with a serial killer who looks charismatic chasing after a helpless girl. Both leads do some smart and some dumb actions. I would say the lead in Midnight might be smarter and the thrill is also more.

In both movies, there's a psychopath hiding a victim, while someone is after him.
I both movies the event takes place in just one day.
The psychopath can easily fool people making them thing he's a nice guy, what makes others dirty.

Handicapped female lead also being chased by a psychopath for witnessing a murder. The big difference is that the female lead actually has a brain and the rest of the characters (other than the villain of course) were also smart and likable.

Cat and mouse game between a serial killer and a chick he set his sights on.

Different storylines, however the concept of stalking is very similar.
Midnight is about the FL being stalked by a serial killer, whereas, Door lock is about the FL believing that someone is trying to enter her house.

Chinese remake of "Blind." Preferred Korean version, but Chinese version good too. I haven't seen Japanese version yet. Handicapped FL fights a killer in order to save her own life & that of another.

very different storyline but if you love Wi Ha Joon as a good inspirational guy in Shark: The Beginning you might like him in Midnight where he's the bad guy! Also Jung Won Chang is also here as a police officer

Handicap young woman is the witness. Would their life in dangerous? Can they communicate well and help in capture the killer?

Can the mentally or physically disadvantage person be a good witness. Would their life in danger if they become a witness to a murder case that the killer still at large?

both "Bad and Crazy" and "Midnight" have Wi Ha Joon in the main role.
the genres of both the show and the movie are also the same; "Action, Thriller, Mystery"

Girl VS psycho killer.
I think Missing you is much darker than Midnight. Also one has happy (in some ways) ending and one does not. Great acting in both.

Both the FL in midnight and ML in Witness act their hearts out. Both involve the respective leads faced with an opponent who seems overpowering. But they give it one hell of a fight. We need more Korean thrillers like this. Nowadays Korean thrillers are going in Hollywood way attach a sex scene and go for some formulaic half assed storyline. But these two movies are an exception.

Both female lead in both movies has some kind of handicap. Their lives could be in danger by recognizing the murderer and the bad guy

both about a girl that is being "hunted" so to speak by an insane killer. they are pretty similar, but I like 'watching' better than midnight. but if you like one, you'll probably like the other.

A chick is being hunted by a crazy guy who is obsessed with killing/posessing her.
