I tried to read this book when it first came out. I couldn'tfinish it. There seem to be at least three themes or storylines in here struggling to get out. One seems to be a reasonably good alternative-history novel based on the idea that the pirate subculture of the 1700s might have formed a revolutionary constitutional regime. Unfortunately, this quickly becomes mixed up with maundering about certain ancient "cities of the red night" and a very great deal of homosexual imagery and fantasy. As the book goes on (as far as I read it, anyway) the main storyline becomes increasingly lost. I ultimately found it both distasteful and so muddled as to not be worth it.

This is written by a 43 year old male who is a true film fanatic. I love all the great directors- Spielberg, Hitchcock, Wilder, Kubrick, Landis, Scorsese, etc. etc."The Unbearable Lightness of Being" was one, if not the most tedious films, I have ever had to endure. Why is it so talked about is beyond me unless, there is nothing definable to discuss. The scenery was bland, dialogue uninteresting and unengaging, even the shots were dull.It's the first film I ever returned to Amazon...ever.When I took Cinema History in College, the Professors I had kept talking about this film as a "must see/ will change your life" sort of thing. Curious, as we never saw it in class (must have been the explicit erotic nature it has at times). Now I think they wanted the girls in the class to see it on their own, because they may have wanted to discuss it with them personally after the class was dismissed, if you catch my drift.I would pass on this one-big time.

For years now, whenever I'm in a contemplative mood, this has been one of my favorite "go to" albums. These rich, harmonic melodies will help you relax without having to suffer the banalities of "muzak."
