The acting was good, it had potential...but it was TOO much. The teacher pushed the boundaries beyond normality. The teacher was abusive, manipulative, narcissistic and incredibly unhealthy. The teacher was toxic, position of power to control and scare young students into complete submission and fear through violence and verbal abuse.

The epitome of toxic.

I was hoping it would become better towards the end, but the ending was not resolute in any way. I would not watch this movie again. It portrays a toxic and unhealthy version of success and hard work that is violent. No one should aim for this or put this kind of behaviour on a pedestal. Other reviewers commenting that this is the type of hard work ethic and motivation that people from the millennial generation are lacking/or in need of, need a serious reality check.
