It is an oversimplication of it, but it's still valid. I did feel the shadow war went by very quickly, and I didn't like the ending with them just making up and running off somewhere. I also guess the lack of a real central figure leading the bad guys was a bit of a downer too, they didn't really have a face they were just a bunch of faceless black ships a lot of the time. While with Earth, you knew who the enemy was. I didn't hate the Shadow War, just loved the Earth War and thought it was the best part of the series.
