It's important to know that Mars in 3D: Images From the Viking Mission is not a traditional documentary film. Having apparently missed the subtitle, I actually thought this would be converted 3D footage from the Spirit and Opportunity rovers that were sent up in January 2004, cut into some sort of Discovery Channel-style special, but this decades-old feature was never designed to be "entertaining," per se. Mars in 3D was made for people at NASA as a document of their work, and it's very dry and extremely technical, with Stanford University professor Dr. Elliott Levinthal explaining the workings of the craft NASA launched and the information gleaned from its findings.
The 3D is also a wrinkle in the viewing experience. Although the film is 3D, and has been given a 21st century overhaul with modern technology, the original elements have technical limitations that are hard to get around. Footage of the surface was taken by two orbiting satellites, with the footage from each one representing an "eye," but to capture two eyes' worth of footage required the orbiter to do a full loop of the planet, which would take several hours. Thus, the shadow patterns in one eye vs. another eye are never the same, and so there are parts of the 3D image that are impossible to completely resolve. Rover footage is even weirder: the cameras were farther apart than normal 3D cameras, and so the convergence point at which the two images resolve into three dimensions is way off on the horizon. When looking at rover footage, it's very unlikely that one will be able to bring the bottom half of the screen "together." The horizons are interesting and look "correct," but that's only half of the image.
The real highlight of the presentation is the electronic music, composed by Michael McNabb and William Schottstaedt. Their computerized compositions, groundbreaking in 1979, is an interesting and evocative companion to footage of another planet. It reminded me of Vangelis' music for Blade Runner, with that sense of technology and artistry combining to create a unique and unusual sound. It's not surprising that McNabb, Schottstaedt, and others who worked on the restoration wanted to keep the film and the music together, because there's only so much score for a 30-minute film, and the film is an interesting historical document, but the music is the only part of the presentation with any spark or energy to it. I don't regret watching Mars in 3D, but the audience here redefines "niche."

The Video and Audio
Music is presented in Dolby TrueHD 5.1, and it sounds fantastic. Some might call the score sparse, so there's a limit to how much of a workout the music will give your sound system, but it's crisp and clear, haunting and beautiful in full HD. One blatant glitch, however, is that the audio from Levinthal's "host" segments (Which is on the murky side) is wildly desynchronized with his lips. Most of the film is actually Levinthal's voice over the other footage, so it's not a big deal, and I'm guessing that this also has something to do with the limitations of the equipment. No subtitles are included, which is a real shame.
The other three extras are all essentially menu-based: an about the project text scroll, credits, and the option to listen to the music in HD, without the film.
