Docu about underwater creatures has stunning visuals.

| Original Score: 4/5 | Jun 1, 2020

A fascinating science lesson for anyone interested in either deep-sea -- or outer space -- exploration.

| Dec 11, 2009

Yes, the work they're doing is mind-boggling and important, but sometimes the images alone are more than capable of speaking for themselves.

| Dec 11, 2009

It's not usual for documentaries to ingest the sci-fi genre, but in this case it's an eye pleasing and mind boggling excursion, beautifully realised and seamlessly integrated into the film.

The far more interesting stuff is back here at the bottom of the sea.

| Original Score: 3/5 | Aug 7, 2008

Once you get used to the "awesome" and "wow"-heavy dialogue, James Cameron's excursion into both 3-D technology and deep ocean trenches delivers some fascinating footage.

| Original Score: 2.5/4 | Dec 27, 2007

Even if these plants and animals did not exist, we may have already invented them, courtesy of those sci fi special effects magicians working overtime for the past decades.

Full Review | Mar 23, 2007

That IMAX 3-D cameras have plunged so deep to record an often bizarre array of sea creatures undoubtedly delivers a certain 'wow' factor, but the accompanying commentary is heavier on breathless excitement than solid fact.

The final shot, in particular, is awesome, and confirms that the sooner Cameron gets back to making proper movies, instead of Boys' Own diversions, the better.

| Original Score: 3/5 | Apr 1, 2006

I want the old James Cameron back.

| Original Score: 2/5 | Jan 19, 2006

[Cameron] speculates that the ocean's depths contain mysterious life unlike anything else on Earth.

| Original Score: 8/10 | Jan 13, 2006

Some great shots of some odd (alien) deep sea fish and a good tie into space exploration, but other than that, the 3D isn't that great and reaction shots go too long.

| Original Score: 2/4 | May 9, 2005

The experience is so immediate and immersive that you actually feel as if you are swimming with the krill.

Full Review | Original Score: 3/4 | Apr 1, 2005

There are impressive rock formations and many other fine things to see, along with an interesting science lesson.

Full Review | Apr 1, 2005

It is a lot more like being there than just watching pictures taken by someone who was there.

| Original Score: B | Mar 30, 2005

It's visually stunning, but [James Cameron] can't resist going slightly too far with its premise.

| Original Score: 3/5 | Feb 26, 2005

Here we know only that Cameron and his bright-eyed young scientists (who take turns narrating) are heading to the deeper parts of the Atlantic and Pacific to observe the environment and life-forms down there.

| Original Score: 2/4 | Feb 20, 2005

| Original Score: 7/10 | Feb 12, 2005

Much of the allure of the film comes from Cameron's easygoing, rather unscientific approach to the project.

| Original Score: 3.5/5 | Feb 7, 2005

It presents complex ideas simply with amazing visuals to wow those from eight to eighty.

| Original Score: B+ | Feb 7, 2005
