I love books that push boundaries. The darker the taboo, the better. And I just happened to be searching for a new book to read and then I saw this - perfect. 
 It has to be one of the funniest, cleverest books I've ever read. I love satire, and this works brilliantly. I can understand why some people might find it offensive (although it really isn't), but I felt part of the point of the book was to show just how stupid a character Hitler was, and how abhorrent his ideas and 'policies' were. Also, without apportioning blame or pointing fingers, I felt that the book was also saying both 'This must not happen again' but also subtly and cleverly highlighting exactly how it could easily happen again. 
 The book also has a lot to say and suggest about modern life and today's saturated media culture, and for me this was where the book was at its best. Hitler's observations of modern life and technology were hilarious. For example... 
 Daytime TV: "Who would choose to watch rubbish like this? Untermenschen, perhaps, who can barely read and write, but besides them?" 
 [Having been exposed to a lot of daytime TV recently and seen things like, 'Cake Boss', 'Bakery Boss', 'Extreme Couponing', etc, etc, I must confess to having the same thought.] 
 The Swedes and Ikea: "In that rotten state of the Swede is permanently on the lookout for firewood, so it is no wonder that from time to time this might result in the odd table or chair." 
 Mobile phone ringtones: "I then heard a noise which sounded like a drunken clown playing the xylophone. Over and over again." 
 Brilliant. 
 Ps. And, also, one of the best book covers of all time.
