I've recently seen the last Kim Ki Duk movie Moebius and I feel I didn't quite get the narrative structure.
I thought the whole film was pretty linear but the last scene, where you find out
that the "monk" that was used to pray in front of the shop is the son,
made me wonder if I didn't overlook some aspect of the structure.
I'm not quite sure but I think that even the gun and the bullets in the drawer may play a role, even though I can't really explain why.
Is there a coherent explanation of the narrative structure?
