Not just a documentary (9 January 2021) Why I watched it? Because I love octopuses and the sea. Why I gave it a 10? Because it was something more than just a documentary. It was a personal experience. It got evident from the start. Great captures and the personal storytelling of Foster along with accurate and calming music did it: I immediately relaxed and put myself in his shoes. The rest was history. Amazing information conveyed along with great scenes and meanings. I liked the format. Most documentaries focusing on animals calm me, but this format was just something else. It was closer to the experience of reading a book for me, and that's something I have never felt before for a movie/series.
