I was despairing at ever seeing this original. Friends had seen it at Film studies at Uni, but I hadn't. Only the second-rate (in comparison) later efforts from other directors. Without doubt one of the most powerfully passionate and emotional movies, ever. A rare 10/10, from me.
Korean releases can be a bit hit and miss; I've had juddery panning movements (that's because you played it on a Panasonic player, Sir)! but this played sublimely.
I would definitely suggest that you choose the second option of the music. I don't think it was written specially and has a rather glib title but it as you would imagine it to be (or dreamed) - soaring choirs, dramatic crescendos where they should be and pained solos to paint an overall vivid and totally compelling experience. It's in great stereo, as well.
You do have to be quite careful in picking the right language though, as simply removing the (standard) Korean subtitles leaves it in French. You have to return back to the Top menu to reset it. You (probably) want it with English subtitles.
That it comes at a bargain price and delivered quickly makes for an absolute must for any serious movie watcher.
