Query: cliche-ridden disappointment

I wanted to like this adventure story blending paleoanthropology and UFOlogy, but the characters are two-dimensional at best and the plot is also stock fare. The frequent asides, in which the author presents less-than-compelling attacks on Darwinism and advances various speculative theories about human origins, might have been more interesting if they were not presented in the context of such a bland story. Likely to be a hit with people who loved the Celestine Prophecy.
