Cycle of hate needs to be stopped.
And that's probably the only reason I am writing this. The movie itself is... So-so. It's not bad, in some cases atmosphere is kind of good, but it is quite cliched and predictable. But... It's also the point of it. Bullying has been even studied, we know how to find it, how to deal with it, and yet it's still there, and is not going anywhere.
It always starts with one thing: someone gets frustrated, blames this on someone they deem weaker or worse than themselves (and "accessible"). The victim, then repeats it to someone they deem weaker or worse then themselves, and then their victim does the same, and so on, and so on, and so on in perpetuity, potentially with potentially locking onto initial bully like an Ouroboros snake. Why does this happen? Because majority of people see a fault in the victim.
This idea was an important point in the movie as well. It is always so easy to blame the victim. Not only in case of bullying, too. But it is also easy to blame the bully, forcing the idea on them, that they are broken, which just reignites the fire of hate. Problem is that there is no difference between these 2 "approaches". Both are incorrect, because they just go to different extremes.
Do you need to support victims, who are suffering? Definitely. Do we need to just pity them? No. We need to teach them the tool to stand up for themselves, and think before they act in a way that may provoke someone unnecessarily. Do we need to out the bullies? Definitely. Do we need to just punish them? No. We need to understand why they are doing what they are doing and go step by step to the root cause. We do not bully them into submission (what was shown in the movie), we try to empathize and show better way.
As with a lot of things in life, this is not something binary. You can't solve the issues in 1 blow, you need to be comprehensive. Unfortunately, the modern trend promote both victimization and bullying. People make stupid decision, and then they are just called victims (of other people or circumstances), and bullies are being bullied back, which just re-enforces the behavior and even create more bullies.
I honestly have no idea how this could be fixed. Turning the other cheek is not a solution in most cases, although under certain circumstances it can temporarily depower a bully. Teaching empathy is also not a full solution, although, it may help. Perhaps we need to start reading our children original fairy tails instead of the modern children's adaptations? I mean, that was kind of the point of those tales, to teach children to be good on extreme examples of bad, was it not?
