I was kind of confused by this. The actual parable didn't start until halfway through the whole cartoon. It was a weird narrative device. I would have preferred if you just told us the story directly. I wasn't expecting that turtle's throat to be slit. It is rather unpleasant.
Well, I guess it made sense with the story. It was nice to see this animation. The voices are quite good too. It is a pretty unique cartoon. It's just not one of your best, IMHO.
