"Would children like it??"
("Would adults like it??" "Would senior citizens like it??" "Would chiropractors like it??")
I can only provide a very personal answer here which is that as a young 'child viewer' I was fascinated, entranced and enchanted by surrealism. I spent countless, statue-still hours watching Cocteau's Beauty and the Beast, The Blood of a Poet and The Testament of Orpheus, or Demy's Donkeyskin. I worshipped Magritte. I'm not claiming this is normal, but there might be something in surrealistic art that resonates very deeply in (some) children, if they're lucky enough to be exposed to it. Anthony Browne plays on it all the time. And as for Disney, it's difficult to ignore the deep passion that the films trigger in most children. Dalí and Disney, a match made in heaven, which could have brought an incredibly large audience of children to the wonders of their union... but which remained, sadly, short, unfinished and experimental.
Not to say, far from it, that we don't have wonderful animators today, whose films for children are extremely powerful, bizarre and evocative. But such experiments in art as this short film are taunting and frustrating, and make you wish that mere financial concerns didn't hinder the creative projects of two geniuses brought together by destiny.
But a world where art wouldn't be tied to financial concerns - that's too surrealistic a thought, surely.
