Very good message.
Stephen Hawking said that if the cosmic phone rings to not answer. Why, because it would be like the Europeans and the Native Americans. We think as a species that we would never enslave, kill, or torture another species but this movie asks the question "Are we so different from them". I teaches a great message for kids of all ages. No matter how difficult finding a peaceful solution may be, they must find it. Now for the age it's hard to choose. You won't receive the full message unless you have a decent understanding of the world. Which for kids takes a long time to kick in. I think that ages 12 and up will get this message but I highly recommend it for kids below that age because it is the perfect time waster for a kid. If you have to do something and want your kid to sit down and not bother you for a hour and a half pop this movie on.
