Making a short about day and night seem like a cute idea - doesn't it? It ends up heavy on the message "be tolerant to those that are different" and could just as well have been about a colored and a white dude tackling racism. Both the animation style and story seem taken from an old 1960s short. Is this really meant as a homage or is it just Pixar being lazy for once I guess it is the former.
I'm torn. This is the single most original use of 3D animation I've yet seen (purposefully using 2D? Effin' crazy!), and yet they threw the whole story away with the radio quote making everything so damned.... obvious and sentimental. Surely there was some other reveal they could have used to present the same message?
