[EX Q]: The Presidential Difference . This book offers insightful, thorough, and well-reasoned analysis of every  modern president, from FDR through Clinton, all in slightly more than 100  pages.  Greenstein concisely but comprehensively reviews all of these  presidents based on various categories -- from charisma to cognitive  abilities to emotional maturity.  Beyond that, he provides a historical  backdrop to each presidency, providing context and texture for each tenure.   This book offered fresh perspectives to most every presidency, and forced  me to reevaluate the Bush and Ford presidencies in particular.  I imagine  most readers will find that Greenstein's book challenges many of their  long-held assumptions too
[EX A]: POS

[EX Q]: I officially hate this book! . I, also, must second Mark Twain. This book is a waste of time! Why do teachers make us read it when we should be reading Tolkien, GK Chesterton, CS Lewis, and the like? Agh. Then, that could just be my wacky taste in novels...     But this was bad. Oh my gosh!!! The descriptions were ALWAYS needlessly long, the conversations ALWAYS needlessly long, the... blah, blah, blah, blah. That's what the whole thing was. Blah. The whole plot could have been totally condensed to a hecka short 200 pg novel and it would have been a million times better! Maybe even good! And I like long books!     This book is terrible. Listen to the warning of a fellow voracious reader and do not waste your time!
[EX A]: NEG

[EX Q]: An Engineer's View . This book was chosen as one of the books to be read and discussed by my men's book club. The author's treatment of the creation is absolutely spell binding and very convincing to an engineer. The way in which the author finds God's face in so many things is interesting and absorbing. I had trouble putting it down, it reads so easily
[EX A]:
POS
