For those of you who have seen this film, it's pretty good even in 2D, but add Blu Ray and the picture becomes much sharper. Now add 3D, and YOU ARE THERE! I got the DVD from Amazon and have watched it twice now. It's simply amazing. So glad it was my first 3D DVD. There were times I thought someone was sitting in my living room, or that I was on a raft on the Colorado River. Film runs 45 minutes, narrated by Robert Redford and has a guest star in Bobbie Kennedy Jr. This is a must for the 3D library.
