I have just finished reading it and had mixed feelings. Some parts of it were brilliant, I thought, especially the descriptive parts. Miller was able to give the reader an almost tactile feel for place and space. Many of the bits involving people felt very disconnected to me - it was hard to warm to any of the characters. The attitude towards women was generally misogynistic, often referred to as a body part, and only valued for sex. Only the Russian princess was given any character development and she was a bit crazy. Some of the male characters were amusing, others just plain sad.
I'm not offended by coarse language, but I generally don't like books where those words are over-used. In this case, I think the f--- and c--- words were used to shock the audience of the day - Miller was successful in that, given the book was banned for so long in English speaking countries.
Overall, it's not a great book by modern standards, but it certainly has its place in history, as it was ahead of it's time in many respects.
So we beat on, boats aginst the current, borne back ceaselessly into the past.
