I picked up this novel because I enjoy the TV series. I have to say that there are very few parallels between the two. The TV series is more of a dystopian soap opera and the novel is more of a fatalistic, alternative history and discourse on humanity. Both are good but the TV Series is much broader, more detailed, and in-depth. There are numerous thematic threads that appear in the series but not in the novel; and vice versa. Of al the Philip K. Dick books I've tried (3) this one is the most readable and enjoyable.
