What parents need to know
Parents need to know that this informative and engrossing documentary takes a close look at the Earth's oceans and the creatures that call it home. Expect scenes depicting these bodies of water in all their glory and reality, and animals finding their place in the food chain (sharks feasting on fish, for instance, accompanied by dramatic music). The movie contains fairly subtle pro-environment messages. Kids younger than about 6 might find the hour-and-40-minute movie too long.
