Saw it too, with my kids. The propaganda angle aside-it was just a bad movie. Plot continuity sucked, and that made it seem much longer than it was. The 98 minutes seemed like 98 days to me.
All the other crap in it-the humanization of animals, exclusion of someone different, raising emotion (song in your heart) to a pedestal above accomplishment and logic, and the enviro-happy crap, was standard fair for movies like this, except they pushed all it of over the top. To the level of absurd.
The final "you gotta be kidding me" was when the UN fixed it and made the people/penguin world one big happy place, where everyone danced and happily ate fish.
I don't usually comment on such things to my kids after movies, but I had to set them straight on this one.
Good grief! The rest of your description was bad enough, but WTF?
But wait a minute ... isn't that just their plot for the world - we'll all eat fish halal food and happily dance pray five times a day ... ;)
(I meant of course your description of the "plot" of the film, not the description itself!)
