Kind of a little disappointed that it wasn't as shocking as people made it out to be. It had an interesting animation style, but it's just another one of those "Oh, Japan" moments that'll get swept under the rug and forgotten.
Well, his scream shows someone's hatred and frustration. And the lyric is strong, vulgar and dark as it's written by someone who hates a certain person and society as a whole. It may sound edgy and yes it is, but I like that this short animation fits the lyric well and it's entertaining to see something unique like this especially as an gore or eroguro fan.
