So this is the ultimate free range kid film. 34 minutes of walking around the dangerous streets of Paris in the 1950s. Notice how the other kids walk home from school themselves. Notice how his mother shoos him out of the house to play by himself. When he is bullied, he outsmarts the bullies with no help from adults.
I loved this movie as a child. It is a beautiful expression of childhood and freedom.
