one of films who reminds the flavor of childhood in delicate manner. for colors, for buildings, for animation itself, for message. far to be surprising. because it is only one of testimonies about the high art of Soviet school of cinema. it is something magic and seductive and innocent and powerful in this short film who seems be the perfect definition of life. sure, it could be an illusion. but the realism of boy, the dream, the body covered by butterflies, the music and the picture of group are pieces from another universe . profound more than realistic. an useful film for the remind of the taste of an age. and, sure, a moral lesson. but, more important, a convincing speech about beauty. and about respect for life.
