This 3D Blu-Ray exceeded my expectations. I was expecting the same episode that originally aired on The History Channel, probably with some gimmicky 3D effects added in (yes, I bought it anyway, hoping that I was wrong). However, I was surprised to see (what I believe to be) some new, 3D interview footage and some new narration recorded specifically for this release. The 3D effects are very good. Seeing tiny Mercury eclipse the giant Sun in 3D is breathtaking as are some of the beautiful images of the rings of Saturn. Sure, most of it is CG, but that's fine because it looks really great. The only poor CG has to do with the spacecraft in which you are supposedly touring the solar system. Really, my only complaint is that there is some substantial crosstalk in many scenes, mostly when you see an object against the blackness of space. If that weren't true, I would have given this release 5 stars instead of 4.
My 2-year-old son is showing a lot of interest in space/planets/astronomy, so I thought he might enjoy this. Indeed, he did. He sat riveted through the whole thing (which, if you knew my hyper son, is pretty amazing). "Is that Saturn?", "Look, the Sun! It's coming out of the TV!", "Wow, the Sun is very hot!", etc. One thing this video accomplished for my son is something I had been unable to articulate to a 2-year-old; that is the sheer size of the planets. The 3D really helps to illustrate this in a way that nothing else can. I think he now has a good sense of how enormous the sun is when compared to other planets.
This video satisfied an itch that I hoped would have been scratched by many of the 3D Imax documentaries out there that disappointed me. It's a good, 3D documentary that can serve as a good demo of your new 3D TV, yet also be interesting and watchable in its own right. "7 Wonders of the Solar System" accomplishes this nicely. Sure, it has a few problems (crosstalk, poor CG graphics for the spacecraft, etc.), but overall I'm really happy with it. Videos are subjective though, so your mileage may vary.
