Earth is the story of three amazing families and their journey across the planet we call Earth. The story is a year in the life of a family of polar bears, humpback whales, and African elephants. To me, the movie seems to be a cross between March of the Penguins and Blue Planet, both of which were incredible.
I realize movie trailers can be deceptive, but I doubt if that's the case here, and it looks like it will be great. I know Disney catches a lot of flack from Christians, but this appears to be a worthy project and cause.
