High art or just junk?
Of course it is up to the individual to make that decision, but I wouldn't classify this as much more than mildly disturbing and even that wasn't the plot, but simply the way it was filmed.
To top it off, whoever wrote the English translation did a pretty poor just of it, or as I read in the subtitles, uncareful.
I'm sure there are those will disagree and I respect that, but if there wasn't a controversial rape scene I don't think it would nearly as popular as it is now.
