I didn't see this in an IMAX theater, but on a 3d HDTV. In searching for material that demonstrates the technology, a shopper can be challenged unless you want four of the "Shrek" movies or horror films that are good for perhaps one viewing.But this film is educational, beautiful and a spectacular subject for a 3D film. The soundtrack by Dave Matthews keeps any of it from being tiresome. The river rafting sequences are well-placed and the aerial shots inspiring.The participants, Robert Redford and Robert Kennedy, Jr., add gravitas without being too heavy with the purpose of the film: Conservation of fresh water and the world-wide crisis.This is a stunning film visually, and the camera spends a great deal of time "in love" with its subject: the American Southwest.

Beautiful film about a one of the most beautiful places in America. Having just come back from an all-paddle trip down the Colorado, I can guarantee you that the film brought back many spine tingling moments on the river.If you've recently rafted the canyon, you'll recognize many places seen only from the river. If you aren't able to raft the Colorado, this film comes as close as you can possible get without going there.The name of the film is "river at risk", and after spending a week in a canyon with experts, I can certify that the title is aptly named. Yes, the film is part lecture and lesson, but how can you not look at lake levels at the Hoover Dam and not understand the problem.Please don't listen to the that other review posted by the Haliburton CEO. I'm not sure he even went to the movie based on his comments. He's obviously very uneducated.Go see this film. It's enjoyable from beginning to end, exciting, and important.

I admit, I was intrigued by this film simply because it is about the Grand Canyon, and I am so intensely interested in it for all that it is. Thus, going into this film, I was simply excited to see the Grand Canyon in visual detail. I came out a happy camper -- excuse the pun -- and don't regret seeing this film.The film is, by means of its own title, a message about preserving the canyon's waters and a viewer would have to be a fool to think that this is a nature film about the details of the canyon's history, geology, botany, etc. Never in my right mind would I think it to be about any of that, simply because of the title and -- of course -- reading what the movie is about ahead of time. (Duh!) That being said, I feel there were many positives about the film that I enjoyed. The cinematography was incredible, and the effects were top-notch. I often felt like I was right there in the canyon, itself; particularly during the river rafting sequences. I often waited for water to sprinkle out onto me (though this is no Disney park attraction!) Also, the soundtrack was excellent and very fitting for the amazing scenery.Sure, there were many elements that I'd have to disagree with. I wouldn't have had so many narrators speak to the audience, and I would have presented more opposing views that counter-argue or give praise to what IS being done to preserve the canyon -- instead of making us all seem like evil-doers who have this centralized plot to overthrow the country's Indian tribes. Yes, I would have to say that a more positive focus should have been placed in the film -- but hey, it's not my thesis.Thus, I liked the film for what it was and not for what it was SUPPOSED to allegedly promise us the minute we purchased our tickets. I appreciate the breathtaking views that this film provided, in just 45 minutes, that not all people may get to experience in their entire lifetimes. For that, I am thankful.

A BIG DISAPPOINTMENT. Don't waste your time or money. This is not a film about the wonders of the vast Grand Canyon. I was anticipating a film that would explore the flora and fauna, the rock strata, the massive proportions etc. Sadly there was no information about the wonders of the canyon itself. I was not prepared for this propaganda packed film. That it was narrated by Robert Redford should have been the first clue.This is a political/earth-worshiping film designed to guilt you into voting for candidates who "care" about the environment and all the poor Mexican families we are killing by irrigating our crops with water from the Colorado River. You will learn about evil Asian trees that have invaded the canyon floor. You will learn about how a tribe of Indians used to farm the river banks and grow various crops but now the river banks are not suitable for this purpose. Gee...I wonder if that's because the Indians don't live there anymore and have stopped working the soil!?! I know when I stopped weeding my garden it became unsuitable for growing tomatoes. Also, you will learn how your spirit is wounded and needs healing. The good news is that you don't need Prozac, Zoloft or any other psychotropic drug from your doctor. No, all you need to do is "connect" with the mighty Colorado by dipping your hand in its healing flow. Mmm, feel the power! In summary this movie tells us that we have been very naughty- The Kennedy's have discovered our misbehavior- and now we must re-connect with the river and replace our shower heads with new water saving models. If we act quickly we can save the dying Mexican families we've been killing by flushing our toilets and sprinkling our lawns.Save your money and go see Ben Stein's film "Expelled: No Intelligence Allowed."
