Yes same here! It was an incredible movie to say the least, and very surprising :) Do you perhaps know the meaning below?:

わたし は さおり で は あり ませ ん. Does this mean that I'm not Saori as in a person called Saori? if yes then how come you don't say it like this to show more polite: 私はさおりさんでありません. Does this work too?

Cheers for the help!
