I thought this wasn't as good as the first one, but it's still very nice. It helps that the animation is so spectacular. I had no idea that Death had to help with the souls of animals. He must have his hands tied up with all the flies and mosquitoes that die all the time. That's even more than the 100,000+ people that die every day. It does kind of seem like you are sounding like one of those PETA people.
If an animal is treated humanely, you can do anything with it. I don't want to go all political on you, so I guess I just stop right there. I loved the voices and how subtle they sounded. You could really get the idea that everything was realistic here. Well, as realistic as it could be.
