As an avid fan of Stargate SG-1, I bought this CD without a second thought.
Thankfully, I was not disappointed. The music is good, but its real strength is its variety. From the intense anticipation of "The Enemy Within", to the grand, yet calm "Nox Theme", this soundtrack just about has it all. Most of the tracks are theme-oriented, with enough variation to keep it from being repetitive.
The only problem with this CD is that it really helps to have seen the episode from which the track is drawn, as the music closely follows the action. Thus, if you have no real exposure to SG-1, this CD loses some (but not all) of its effect.
As most printings of the Trilogy include a map, this book may seem unnecessary. In my opinion, the converse is true. The small map printed in the Trilogy is nothing but an appetizer compared this atlas. While the book was printed in only two colors, it has excellent detail. I found the maps of the battles quite useful, giving a better idea of how the battles progressed. The book also details the times covered only slightly in the books, as well as the era of the Silmarillion.
In addition, this book is highly recommended as a supplement for those watching the movie. Tolkien created a universe so vast that it is easy to get lost, especially in Peter Jackson's excellent movie.
