The animation is top-notch, but as visually inventive as some of the shots are, the entire message is there in the first few seconds. Happiness at least had the contrast between the bleak visuals and the serene soundtrack to provide a point of friction. Not that this film's subject is an issue that requires a ton of nuance--I get that the whole point here is a reminder of how goddamn horrible we are--but once that's established the film just has nowhere to go.
