Does the book...(spoilers)

...go into any more detail about the nature of political/social life of the "era" when the movie starts? The nature of some of the dream outcomes, like the plague and the draught?

I think they would have added some narrative interest in a movie that took itself a little too seriously and whose narrative conclusion in "it was all a dream" seems kind of easy and unoriginal.

I liked the notion that the dream "outcomes" had a sense of unintended consequences associated with them, but would have preferred that they spent some time examining the outcomes from a sociopolitical perspective and not just as part of the psychological/philosophical argument between Orr and Haber.
