Deserved revenge in the film business must come rarely. I don't for a minute believe that Hertzfeldt is blameless in how he dealt with "the suits," but I've had enough dealings with them to serve them any insult possible.
I first encountered Hertzfeldt's work in "A L'amour" done before this. It has him approaching different women and saying innocuous things "Betty, those are nice shoes" and having her chainsaw out his heart and eat it.
This stuff is along the same lines, a little less powerful and more uneven. But what makes this something you'll remember for a long time is the stuff done after the initial rejected bits and the faux ads. Its the stuff where the cartoon itself begins to disintegrate.
It is a literal example of self-referential folding: the paper crinkles and destroys the world.
This is probably the second best of his stuff. See "Genre" if you can.
