1/5 Shameful!
  by Harold Edward Wills (Hagerstown, Maryland USA)
Got this movie because of the reviews and my love of 3-D on my HD TV. First, the glasses had the red and blue reversed, making them unusable, but when viewing this mess, with glasses I had, there was no part of the experience that came even close to being 3-D. Unless I got a very bad copy, this was as dull in content as I would ever wish to experience, so the only thing that could possibly have saved it would have been spectacular 3-D.
National Geographic has really gone way down if they consider this entertainment, and as far as the other reviewers go...well! Maybe I'm not as easily entertained as they are!
Amazon, as usual, allowed me to return it.

5/5 Amazing Home Technology

I first saw this movie in IMAX 3D and was truly impressed with a really good storyline and amazing 3D effects. When I saw this movie was released on Blu-Ray in 3D I was hesitant thinking the 3D at home would be a joke. I was proven otherwise. Even on the comfort of my couch the 3D is amazing. You still get all the feelings of the screen coming to life as well as objects projected so close you feel could be hit by them.

2/5 Nothing Great

The 3d effects was nothing to shout about and so wasn't the documentry,In 2d,it was decent,but the 3d images were useless..Go pick up the Polar express 3d ,My Bloody Valentine 3d or Hannah Montana 3d

Stunning, amazing, informative and spectacular! Comes with 4 pairs of cardboard glasses. Do NOT use those (they're OK, but not great though!), Get plastic ones instead! Better fit, better view! Turn all your lights off, watch that DVD at night! It'll take your breath away! I really enjoyed it! Highly recommend!
