Oh dear God
That was beautiful. I have watched this before and I apparently didn't get it because that was amazing. I didn't see it as political at all, but I did enjoy the personification of pigs into humans and the joke replacing drugs with coins and needles or whatever with piggy banks.
The animation was nice, the crude, jagged lines made it a lot more unique and helped bring out the special story instead of it just being a good idea hidden with the usual tweened up, smoothed graphics.
I would love to see more work similar to this.
