In praise of ordinary life vs obsessed artistic way of living.
I enjoyed last scene like others. At first I was assumed the point of view omniscient but I noticed a fine transition between two first person in two different scale. When the narrator changed his subject from Hong Sang-soo's Leading actress to the Novelist's Leading actress.
"The Novelist's film" here express the director's manifestation through the form of film and at the same time paradoxically stands against Hong Sang-soo's film itself. I liked this paradox.
