I'm not gonna read the book, so what's the central issue that was ducked?
On it's own this film is just unfortunate, but in comparison to the book it's unforgivable. The cynical, interesting characters of the book have become flat, either ridiculously heroic or villainous. Even worse the film ducks the central, controversial issue of the book.
Smoking. The film changes the central topic to one of gun manufacture instead of cigarette manufacture. There's actually a whole discussion in the book about the difference between cigarettes and guns and why the manufacture of one makes the company liable while the manufacture of the other does not. I doubt that anyone involved in the film read the book that closely.
