Why only four points? Bodies pave the way of the main characters. Minor characters are routinely shot ratzfatz, slogan "Strong men and their guns at hard way". Maybe that helps in the American market. For me, a unguter aftertaste.
Still exciting to read. Up to the closing. In the final pages, it's just a matter of who is killing whom and in what order. I thought that was boring. Because one suspects so who survived or can read it quickly.
So: With restrictions highly recommended! I will also look for other books by Stephenson!
