Well here you can see everyone's reactions to the movie.
Yumi is frightened by the movie.
A-Ko is 100% focused on the movie.
B-Ko is upset about having to pay for the movie.
Fuko is very interested in the movie.
Mika is scared but forcing herself to watch.
I wanted each character to have a different reaction to what is going on. As far as what is going on in the movie, your guess is as good as mine.
