Thanks for mentioning this, as I sometimes forget to bring it up, though people should be aware of it before they go see it. I agree that scene is very uncomfortable and difficult to watch (very much intentional on the part of the director), but I personally felt like it did have a important role in the story and character development, and was a pretty key part of the film in general.

Just a warning though, as someone else mentioned, big CW on this for an SA scene in the film that’s difficult to watch.

He basically ripped entire scenes from the movie without getting any kind of permission and then copied it again with Black Swan. Good article about it here: https://animationobsessive.substack.com/p/the-real-history-of-perfect-blue
