HI, I am looking for suspens/crime/thriller/detective movies, full of supsens. Any suggestions please?
Here are some movies that I can recommend!

Korea

Beautiful Sunday
The Man From Nowhere
I Saw The Devil
Midnight FM
Neighbors
Diary Of June
Rainbow Eyes
Blind
Arang

China

The Bullet Vanishes (detective)
I second the Man from Nowhere. I also suggest Someone Behind You and Sector 7 (this one is more of a sci-fi thriller).
I second: The Man From Nowhere but it's more of an action thriller than a detective thriller. I also second I Saw The Devil which is more of a psychological thriller and The Bullet Vanishes which is a detective thriller. I will add Memories of Murder and Montage that are one of the best detective, mystery, suspense thriller movies made in South Korea. There's also The Chaser which is a great suspense thriller.
