I was greatly disappointed by this title.
The focus was often very poorly done and the depth of field was bad.
Constantly having to re-focus on the screen caused eyestrain and ultimately a headache. There was little or no screen popping from the 3D.
The female narrator's voice was both monotonous and stilted.
I have to agree with another of the reviewers who added that he had seen more professionalism on YouTube.
I concur, there was little or no quality in this production, save your money folks.
There are a lot of Good 3D documentaries out there but this is most definitely not one of them!
