Not quite what I was expecting.
Similar to Mad Max but without the cars. It is a post apocalyptic story where Eli is traveling (walking) across the country to deliver his book. Unlike a lot of people he still lives by morals and rules. This leads to a lot of action scenes and interesting locations as well as a lot of slow motion. Densel Washington was a good pick for the role, he brings an intensity to the role.
The girl sees Eli reading the book and is forced to tell the boss, Carnegie. Carnegie senses that this is the book he has been looking for and wants it at any cost. Eli will not give up the book for any price, this leaves only one possible outcome, war between the two.
