Very well executed

Excellent but underrated film

Through painfully honest and emotional moments, the movie becomes irresistibly relatable

This movie tries so hard to be funny, yet it falls flat every time. Just another example of recycled ideas repackaged with women in an attempt to appeal to a certain audience.

A 3D documentary chronicling filmmaker James Cameron's diving expeditions in his Deepsea Challenger submersible. One of the best parts of 'Deepsea Challenge 3D' except the ocean and just Cameron's explores is that it also showed some small videos from Titanic (1997) and even tho that film is not my favorite Cameron film i admire the man's heart and what he went threw to shoot all of those stuff both underwater and not. But this one really shows some excellent pictures of underwater but also the adventure that waits the well known director. As i said before James Cameron is not a perfect person but he is still a genius and documentaries like this quite prove my point. (8/10)

"Deepsea Challenge Review" In this epic documentary, James Cameron takes to the sea in the name of science. James Cameron is known for his work in hit movies such as Avatar, Titanic, and Terminator. In this documentary James Cameron has pulled together an elite group of engineers that share one common goal to reach the deepest part of the ocean, the Mariana trench in a submarine.The documentary "Deepsea Challenge" shows the challenges James Cameron and his team of engineers had to endure while trying to build a submarine way ahead of its time. They had to consider pressure, lack of light and many other challenges while building the submersible. Deepsea challenge focuses on the ocean and how tectonic plates have completely altered the face of the earth. The Mariana Trench, the trench they visit in the documentary was formed by subduction, which occurs when one tectonic plate goes under another. I liked how safety was always their first priority. They did multiple test dives at different depths so that if there was any problems with the submarine they could fix it before the actual dive. I also enjoyed how they named the animals they saw in the test dives such as the angler-fish. It was also nice that they explained how the Mariana trench was formed.I learned from this documentary that with enough time and enough determination that you can do things that the average person can not. If your life goal is to reach the bottom of the ocean then you can. I believe that other people will also learned the same thing from this documentary. I believe that adults that are interested in ocean exploration or any type of exploration will find this documentary enjoyable. I would not recommend this documentary to younger children because they tend to have a shorter attention span and this movie has its fair share of long and boring moments.

Ricky's long term goal is to resurrect his goldfish named Sparky, who he lost at the age of 6.

I had been been looking forward to this for years now. I love good documentaries, about science, the cosmos, nature or history. I love submarine movies. I am a geek. If anyone was going to love this, it was me. But I didn't.For starters, the geek in me was very disappointed next to no time was spent showing off the technology. How does it work? How do you build electronics and camera's and other equipment that can resist that pressure? How do you navigate or communicate at that depth ? I was dying to find out, but I learned nothing. Even when things go (very) wrong in early test dives, no explanation is given of what failed, why it failed, how they solved it. Meh!Then there is the "plot"; I get it that some time will be spent on Cameron's history, why he wants to do that etc, but it takes forever. Is this movie about an expedition or about James Cameron? If only they spent half the time that Cameron claims to glorify himself to talk about the sub, I might have like this.Finally, there is the (anti)climax of the film. Not sure if this should be considered a spoiler, but when he finally dives to the bottom of the Marianas trench, it seems like he spent all of 2 minutes on the bottom and the most exciting thing he saw was some mud sliding. You don't even get to see a trench or underwater relief, let alone anything alive. Just sand. Now I get it, this was a documentary, not a scripted movie, but really, if that is all there is to see there, what a waste of time and money. Not too mention a waste of my time.

The first thing that stands out about Deepsea Challenge 3D is that a lot of effort has gone into documenting the missions in a cinematic way. There are cameras everywhere: mounted on smaller submarines to show you the bigger ones; built into the walls; carried by divers; etc. All this is fluidly strung together to recount a fascinating story, and supported by a dramatic soundtrack.The documentary doesn't only show you the Challenger Deep mission, but everything that has led up to it, and this includes tons of film-worthy material. We are given a track record of Cameron's almost romantic relationship with the deep, and this includes some deep sea exploration missions he has conducted using submersible robots, taking us into the monumental wrecks of the Titanic and the German battleship Bismarck.A lot of attention is given to the design of the Deepsea Challenger itself, and the engineering exploits that were carried out during its construction and testing. Creating this one-of-a-kind "metal coffin" is an adventure in itself, especially considering that the conditions down there are in many ways more difficult to deal with than outer space.Cameron's narration of his expedition log bears an uncanny resemblance to Jake Sully talking about Pandora, and while there are no straight-out action scenes, Deepsea Challenge 3D feels like a science fiction movie in the way it draws you in - but this time, you know that everything you see is completely real, even the crazy stuff. Some scenes are very tense and will have your jaw hanging in disbelief, such as the dramatic submersion from deck-mounted cranes in sketchy weather, or the extent of multiple systems failure during one of the manned test dives.In the end, Cameron says he hopes this project will also inspire children to live up to their dreams, and indeed this film is likely to mesmerize most kids who see it. It sure made me feel like a kid, and it's very inspiring to witness the adventures of real life explorers.
