You guys gotta quit bein haters that old dude is a bad mo fo He was nearly torn in half and still went back into the water. No Respect. some of you play in the river and get scared.

the two main people were lame but there was some incredable footage and the old man almost drowns twice so it was at least ok.

The birds ironically were the only interesting part. Why are we wasting our time and money on finding out how we can invade the territories of other creatures without getting mauled?! Test out a chemical in the ocean, do you know how much water that is, Doc? How about we either stay out of the water, or enter at our own risk? Why do humans have this idea that we rule the world and should have freedom to go absolutely anywhere without fear of retaliation? That's not how the real world works! I thought this would just be a nice look at underwater world, which is always calming nomatter where they go, can we get some of those?

I love watching films about sharks but this is horrible!!! I had to turn it off about half way through it because it was full of crap! The experts were not only boring and bland but made themselves look like two awkward old people who are about to get themselves hurt and not by the sharks but just out of stupidity.

Visually stunning and intellectually entertaining. Granted, these marine biologists and divers aren’t the world’s greatest actors, but if I wanted to watch good acting I would have gone to the movie section of Hulu, not the documentary. To say this documentary is intellectually lacking or defunct is a little harsh. I think it has its corny moments, but it’s unfair to call it tawdry. Overall, I thought it was a good piece.

The blatant need for people to glorify their own "heroics" never ceses to amaze. This chopped up editing fiasco does nothing but cater to the uninformed. CUT!!!

A lot of mis information and a great example of a blatant lack of knowledge. these people are as useful as a first grade class and everyone involved with this should be embarrassed.
