The movie is really good. It's filled with lots of interesting things to see and learn about.
I also really appreciated how they touched on over-fishing and what humans are doing to destroy the oceans. I was about brought to tears when they showed the shopping cart sitting at the bottom of the ocean floor. It's incredibly sad what our species is doing to the world.
I would have liked them to speak on that issue longer, but I realize they don't want to turn off a large part of their audience. I think they focused on these issues long enough that those watching will get the point.
Two thumbs up for the Disneynature "Oceans" movie!
