Army guys might dig this book, I, on the contrary couldn’t even finish it! It reminds me of World War Z: an oral history of the zombie war because they are both told by different voices around the world narrating the events leading to the zombie war and in the case of Robopocalypse, the robot rebellion.
I found the book very army like and technical. Also, if saw the I, Robot movie with Will Smith you already have an idea about what robot rising is about and might enjoy this book.
Why did the robots rebel? How does it end? Only God, Wilson and those who could stomach to finish the book know! Because I gave up before my eyes went robotic on me and rebelled to read anymore.
Steven Spielberg is making this book into a movie which I think will be awesome because it stars Chris Hemsworth and you know how hot this Australian guy is :- ) and being the latest Midas of Hollywood everything he acts in turns into gold.
Different opinions here and here.
