Shockingly eye-opening movie.
This is the perfect example of how bullying in school can get to a point where it turns into harassment, mental and physical.
Not only does it show us, the brutality and force with which the whole class crushes one individual, but we also get to see the victim's background, his thoughts and aspirations.
Despite the cruel ending, we can all identify with Joosep and find some innocent motives (God's law) even in his very deed of revenge.
