I kept wanting to touch the images, especially in the opening sequence. This movie just has to be seen to be believed. It literally picks you up and sets you right down onto the track. I thought I was sitting on that banked oval!. The sound was excellent also as I kept turning to tell some patrons to be quiet. Then I quickly found out the voices were part of the 'surround' dialog. Ear-blowing as well. The sound could have been a bit louder, but you can't have it all. And Keifer Sutherland's narration was, well--Keifer Sutherland. You can't go wrong with him in any role. I could sum this film in 5 words or less, but IMDB needs 10 lines for my review. What can I say? I give N3D a perfect 10 as a 'documentary' movie. Now I want the IMAX 3D experience at home...dang!
