Fascinating film. Very well done.
Very smart people can be seduced or enamored with rather foolish ideas.
I'm not expert in educating all children...but some kind of authoritative approach is the best way to go. It was painful to watch how the children struggled, especially in the case of expelling Jiovanni, with the leadership role that was thrust on them because the adults in charge abdicated their responsibility to make the discipline decisions.
There were beautiful moments though. Children can express such wonder and exuberance.
