Midnight

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.

Midnight is a movie about a serial killer who stalks a handicapped, yet very determined and clever girl. The serial killer, played by Wi Hajoon is very similar to Yuno in 'Somebody'.
Both have a plotline of a handicapped girl being tormented by serial killer - in 'Somebody' the girl is in a wheelchair, while in 'Midnight' she's deaf and has to get away from her assailant using wit.
Both serial killers are psychopathic and have a few endearing moments with the victims.
Both girl leads get revenge on the killer.
Both are suspenceful.

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

While this may not have a "psychotic killer chases witness" premise, there's the cat and mouse element between an innocent civilian and a serial killer and the chase is really thrilling. The fight between the main characters in "Monster" was a more exciting one in my opinion, however both were entertaining to watch.

Então os dois tem o grande Wi como vilão e dentro do mesmo seguimento de crimes contra mulheres.
Ambos falam de assuntos polêmicos e que põem a fragilidade das mulheres em pespectiva.
