Haven't yet decided how I feel about this book, but I'm glad I read it. It can definitely go on for a while, but there are enough little gems scattered throughout the book to make it a worthwhile read.
The writing is definitely the best part of the book. Pretty much all of my favorite parts were conversations that sort of throw the many political and social viewpoints in the book against one another. Rainey and the bartender talking about the Big Store, Rheinhardt and Rainey's philosophical discussion near the middle, and the Rheinhardt, Bingamon, Jack Noonan all stand out as the best the book has to offer.
The story got me interested initially, but it takes a while to get into it and you never really learn much about the political stuff until the end. A lot of the book consists of characters talking, drinking, and speculating about themselves and the world at large. Not always bad, but it can get a little heavy handed and repetitive.
The characters range from relatively complex and interesting to one dimensional. Rheinhardt is probably the most developed, but that's not saying much. He's detached so unsurprisingly things go wrong for him, which he essentially takes as justification for his cynicism and detachment. At various times he realizes that he's really largely responsible for all the pain he's caused himself and others, but just collapses in on himself rather than make any meaningful changes.
Rainey started out as an interesting character, but sort of gets lost in the shuffle. He's constantly looking for meaning in his life but can't seem to get past this middle-of-the-road, half-measure existence. He pretty much lets the perfect be the enemy of the good through the whole book, and when he can't bring himself to manifest his ideals as actions, he finds someone who can do so, and attempts to pretty much "tag along." Unsurprisingly, he gets cold feet and screws things up for both of them, and somehow this is the decision he feels finally lets him off the hook. Yeah, Rainey kind of sucks.
Geraldine was by far the most disappointing - her story started off really well and was interesting (her scenes when she first arrives in New Orleans are great social commentary), but as soon as she becomes Rheinhardt's love interest we see less of less of her, and those scenes pretty much boil down to, "Why doesn't Rheinhardt love me back?" Not surprising that a dude from the '60s can't write great female characters, but the strong start made the fall that much harder.
So looking at all this it would appear that I didn't like the book, but I still keep thinking about it so there must be something there. While the characters are generally unlikeable, they're pretty well developed and the internal monologues and discourses are really well written and compelling. The book definitely made me feel something, it just wasn't anything good.
All in all, it's definitely a good book, but perhaps not a very enjoyable one.
