What with the coming of Avatar - and indeed the return of James Cameron - I figured it was about time I got off my arse and checked out those couple of undersea documentaries he made early on this decade. First through the letter box was Aliens of the Deep, and what is definitely the weaker of the two documentaries.
That said, it's still fascinating. A mixture of technological and natural eye-saucering. It doesn't carry the same poised, descriptive and imaginative commentary as David Attenborough does in the exemplary Planet Earth and Life (both of which have featured undersea episodes, covering some of the very creatures gawped at in Aliens of the Deep).
Nothing particularly deep, but alluring to those of a James Cameron fandom persuasion, and those who want to get a taste of the experience of deep sea exploration.
