Sure, there was the whole battle for Earth, and human struggle thrown in. Though, Hubbard seemed intent on driving home his points about mind control, and pretty much called psychologies modern day clowns.

All right, ignoring the rant aspect of this story, it's okay. It keeps your interest for the future of humanity. Some of the little sub-plots go on for too long, but didn't distract too much from the story. What really hurt this was when the story ended. The main plot was resolved about two hundred pages before the book did. Almost as if Hubbard had to find some other story to fill in the gap, he brings in a new race of aliens that Earth has to fight, and continues his stereotyping of humanity (the remaining Chinese are good servants and cooks, the Swiss are good a fixing little trinkets, etc). The story wraps up the few remaining open sub-plot points, almost insulting the reader in the process. This is also the point where Hubbard goes into the back-story behind the Pschylos, seeming to warn the reader about mind control. Though, by this point I could care less, I just wanted to end the story.

In the end, it's better than the movie, but not by much.
