That's a good video. I don't often like animal analogies like that because they tend to vilify animals and make it easier for people to hate them. But I think the video was good and acceptable since it was animation. And well, I just like he song, too.
The song is inspired by 1984, and the video sort of has an Animal Farm vibe to it. It fits so well.I do fear pigs are rather maligned in the whole animals-as-humans metaphorical scheme, both here and everywhere else.
