I wish I would have done more research before purchased "Earth." "Earth" is a basically a condensed, child friendly version of "Planet Earth." It's great if you want to expose your children to the wonders of planet earth, but they lack the patience to sit through the BBC series. I also thought the narration left something to be desired. It did not really add much to the film and felt "dumbed-down." Disney's choice of James Earl Jones was also kind of comical, as I felt that Darth Vader himself was teaching me about the earth. The movie looks great, but we have seen it all before. If the series "Planet Earth" never came out, I could easily give this 4 stars, but "Earth" is just recycled footage with dry narration.
