Beautiful documentary / movie. I really had no idea what this movie was about, except for an octopus had to be in it. I thought I'd be switching to another show but before I knew it I was looking for a tissue (hmm, maybe a few of them!). It's a wonderful way of learning (or teaching) about another part of the world most children, and probably some adults, aren't familiar with - what's below the sea, oceans and the different types of fish, sea creatures, plants - the beauty and fascinating world of Earth's oceans. Parents may find the ending difficult for younger children to watch, but at the same time if they're at an age to learn about death I think this could be a way to teach them.
