PROBLEM: Review: I REALLY DIDN'T CARE FOR THIS BOOK AT ALL. I FOUND BOTH THE WRITING AND THE STORY LACKING AND UNIMAGINATIVE. I BOUGHT THIS BOOK WITH AN INTEREST IN FANTASY THAT REVOLVES AROUND ELVES OR FEY. I WAS SORELY DISAPPOINTED BY THIS BOOK. THERE WAS VERY LITTLE ABOUT THE MAIN CHARACTER'S FEY HERITAGE. THE STORY ITSELF IS CHOPPY AND THE CHARACTERIZATION WEAK. A WASTE OF BOTH MONEY AND TIME. I WILL NOT BE READING ANY MORE OF THIS AUTHORS BOOKS. 
 Polarity: Negative

SOLUTION: True

PROBLEM: Review: This is well acted, beautifully filmed...and pretentious exitentialist tripe. There's a difference between TRYING to be deep and serious, and being deep and serious. This movie doesn't know the difference. Long and slow. 
 Polarity: Negative

SOLUTION: True

PROBLEM: Review: While I believe in discrimination, I certainly can't believe what is in this book. It is an unsubstantiated smear campaign to rally the troups in higher ed to claw again for the preservation of academic freedom- a rally which falls flat. 
 Polarity: Positive

SOLUTION:
False
