content: Picture was not 1080p blu-ray quality. I own and watch many blu-ray and this one was more like DVD up-converted to 1080p. Maybe it's the IMAX camera, I was very disappointed in the picture quality. Some of the clips are not even HD, just standard SD. I watch all my blu-ray on a 106" screen with high quality 1080p projector and this was terrible. May be okay on a smaller size HDTV but you will be disappointed with larger size HDTV or screen.Roving Mars mainly focused on the beginning of the project up to the point both rovers landed at Mars. I felt cheated, didn't show any of the Rovers exploring Mars but the initial landing. I had hope to see more actual pictures of Mars, but only a few shots were included. I saw much more exploring and pictures of Mars from the Discovery channel show on this project than this blu-ray. Very disappointed in my purchase.
