Very touching.
As the song and animation starts off, it seems like it will be a cute and happy little ditty with a moral that's primarily about the things that we share. Then the keys change, and the university comes into play.
As expected, when the music becomes more horrific, the animation quickly follows. The only one with sense enough to try and break the herd mentality is cornered and it's suggested that he has disappeared from the rest of society.
It's actually quite reminiscent of how many people today have a herd mentality, and the ones that are smart enough to figure out what's going on and try to break free are the ones that aren't heard from anymore.
There's so much more that I get out of this, but I fear it would turn into a political rant, so I will stop there. This is a great animation with a great song and a great moral when put together.
