This is an excellent, awe inspiring, documentary video on the beginning of the nuclear age. The digitally restored films of nuclear explosions are quite spectacular. William Shatner is an excellent narrator and the soundtrack is very good and fits the film perfectly.
There were some things in the film I didn't like at all. At two parts in the film, they show nuclear testing on animals, and it is quite horrific seeing these goats, pigs, etc. being chained up and slowly dying. It is very awful and not for the squemish. They also showed victims of Hiroshima, but it wasn't nearly as graphic as the animal scenes. Also, the 3D section at the end of the video is very disappointing. It is mostly narration and only shows one or two explosions, and the 3D effect with the glasses does not work at all.
Please note: I purchased the VHS version, not DVD.
