I am Korean.
Personally, I like it if it's done well and not overly done, which IMO it rarely is overdone. I think it adds a sense of reality and focus to what can be a very busy scene.
It's rather pointless to me. I'm already focusing on what I want to look at which makes the DOF stuff reduntant.
But then I also intensely dislike any effect that brings the game's camera into the mix as an actual object. It raises a lot of annoying questions in the back of my mind while I'm playing and I find it disruptive to immersion.
I start thinking things like, "So I'm not the guy on the screen, I'm the camera man?"
