This short has everything you would expect from a Golden Age-period Disney cartoon - beautiful colours, evocative draughtsmanship, awesome fluidity of action, incredibly inventive variations on a minimalist plot, good comic violence. There are also some complex themes, such as the violence necessary just to survive in suburbia, a very Bunuellian notion. The film's great merit, though, is in prefiguring by seven years Hitchcock's 'invention' of Scottie's dolly/reverse shot from the world's greatest film, VERTIGO (you know the one, where he's looking down, and goes all wobbly). You never read THAT in the history books.
