I first watched Namu when I was about 12 - the lesson it teaches has stuck with me all my life ... don't destroy nature just because you don't understand it or because you can. Namu is the "first" killer whale move, but it's also one of the first movies to take a naturalist point of view, that all creatures behave by the laws of nature
except man. Namu is a great film for kids to help them go beyond assumptions and try to see life from multiple points of view. Robert Lansing played the character of the marine biologist just right – intelligent, slow, deliberate, and even when angry he held back, not lowering himself to the level of characters that were blinded by prejudices – the character is sometimes reminiscent of Atticus Finch in To Kill a Mockingbird.
