This is the first of Philip K. Dick's work that I really haven't enjoyed. It wasn't bad, and there was part's I enjoyed, and it was an interesting structure, but I also found it boring and a struggle to finish. The "exegesis" parts especially were a chore that I started skimming towards the end. I also found parts of it uncomfortable - it's semi-autobiographical and I didn't really enjoy reading PKD's real psychological breakdown.
