The Monster is attitude. Our own, our fear, our fear of what others will think. The excuses we give to each other and to ourselves. Our need to belong and need to be individual. Our need to be understood and our need to be rebellious. How we wish the monster would just accept us for who we are and what we think. Instead the Monster just keeps on growing knowing that we will just cover up what it is even if it does more harm than good.
The film starts off by suggesting that the behaviour and change in that behaviour of a school pupil could be down to a teachers bullying. As the film goes on incidents are replayed from different points of view and explanations become blurred. There is no easy answer and no easy ending. But the film does offer hope that one day our Monsters and attitudes to each other will change for the better.
