This Blu-ray Disc has excellent picture and sound. However, I found the movie itself to be lacking. First of all, the content of this movie could have been narrated in 15 minutes; as a result, the movie seems to repeat the same concept over and over again therefore being very predictable in where it is going.Second of all, the movie was very obviously designed to be watched in 3-D. The effect is just not the same in 2-D as fish swim towards the screen in 2-D and objects awkwardly jut towards the camera. While I'm sure this movie was engaging in 3-D, watching at home in 2-D was actually rather boring and non-engaging.I've thoroughly enjoyed other National Geographic presentations on Blu-ray such as Relentless Enemies, however this one seems to be short on substance and designed for color 3-D delivery which is not really possible on Blu-ray yet. I'd avoid this despite its interesting sounding title.
