Old Boy (South Korean). This is probably the sickest thriller I've seen - psychological with many-a-twist. Definitely recommended.
I saw that film too. It was a long time ago. It was very sick with alot twist and great movie!
I don't watch much Korean films. Old Boy and Tae Guk Gi: The Brotherhood of War is only Korean film I saw.
You watch the whole trilogy? I stop after Old Boy.
I don't want to spoiler the ending but I don't understand the ending at all?
Maybe the English Subtitle wasn't translated correctly from Korean language back then.
I got no idea what happend at the ending because it doesn't made sense.
