In parts, I was on the edge of my seat. Who would have thought you could get so involved in the life of an octopus. It was a very calming film, going along at its own pace, slowly through the diving underwater narrations of the Craig Foster the cameraman and documentary film maker. This is a worthwhile film to watch, but be prepared for calm even tones. Maybe not the best to watch when you are already sleepy, although there are spellbinding times in the movie where you can't look away!
