I've seen 3 so far and they're pretty damn depressing. The movies are well shot but they tend to be about 15 minutes too long and the endings are fucked. 1) Old Boy - Different revenge flick in that he just goes after the bad guys that capture him. There's some sick shit in the movie and the ending was probably the most depressing of the three. 2) I Saw The Devil - The Old Boy characters plays a psychopath. First 1.5 hours was good cinema. Loses its luster after that due to unrealistic situations/dumb moves by the main character. Worth watching just to see the acting of the psycopath killer. He goes from harmless to crazzzzy in convincing fashion. If someone acted like that in the streets, I'd be shitting my pants. His demeanor was terrifying. The ending was also tragic. 3) The Man From Nowhere - Reminds me of Man On Fire. This was the most fun out of the 3 because the main character was actually kicking ass throughout the whole movie. Ending was sad but in a good way. The first 2 movies doesn't have satisfying endings and it makes me uneasy. Not really a fan of those movies, so I think I'm done with Korean revenge flicks. It's too much for me.
