Now this is a reason for Blue Ray. Real nature photography in the multicolored, magnificent depths of the ocean. Its like a super sharp, high definition version of those old Walt Disney specials they used to show on The Wonderful World of Disney. The ones where you'd groan because you'd rather have cartoons or Kurt Russell doing something cool, but then it sucks you in. Yeah this is waaaay better tan those and worth the price. I recommend watching it on the biggest screen you can. It will be so worth it.
