i read this book 20+ years ago, in italian. i remember been surprised because i couldn't see why this book was so famous and regarded as a masterpiece.
reading the original version i can tell the the first part, at least until the 'conversion' of the main character, is masterpiece stuff. after that it becomes predictable and too cheesy for me. the ending is simply out of line with the rest of the story, and that is why my star rating is only 3.
the setting of the story, the world that the authors build is incredible, but rings true. it could be the future, it could have been the future, seen from the '50s. this is the best thing of the book. i didn't particularly like the characters, but they fit the story.
