Not even for the airplane . If you enjoy a good, tightly plotted thriller -- read something else. This flabby, clunky and completely unbelievable story labors to its silly ending wheezing and gasping like an overweight commuter trying to catch the 8:45. All of the characters are two dimensional and if you don't figure out the ending hundreds of pages before it arrives you are unconscious.

Ex Output:
NEG

Ex Input:
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 Output:
NEG

Ex Input:
The Best Picoult So Far . Every book by Jodi Picoult grabs you by the heart and doesn't let go. Mercy stands out from all the rest. You will not forget this book or the people in it for a long time

Ex Output:
NEG
