The only thing I didn't understand was it was a movie

It was good to watch it. It really describes what is happening in our current society now, a lot of bullying and people who are silent out of fear for themselves. I hope it becomes widely known so that everyone knows what we are experiencing now.
Since I have lived this role and seen it happen to other people, I hope that if you see something like this, do not remain silent in the face of injustice. What you saw, you don't know what might happen next time to the person or the bully in general .
