The New York Times book review has a piece on The Idea of Nature in Disney Animation (Amazon UK) which discusses the pastoralist view of nature presented (think Bambi which outraged hunters in 1942 on its release) in its films.
Disney does sentimentalise the children’s stories that it creates and arguably always has done. The Mouse is not reality’s friend (for some reason I don’t see it re-doing Watership Down) but the underlying stories do tap into a consciousness which surface periodically. What Disney has in enthusiasm is tempered by its simplistic viewÂ the world – good v bad – and that ultimately damages its message.
Perhaps it greatest challenge would be to explore some shades of grey?
