PROBLEM: Review: When I am in need of a product I spend a lot of time doing research. Not only are the costs of the product and shipping/handling charges important but also the speed, accuracy and dependability of the company/person involved. I highly recommend this source to be checked out when searching for specific products. 
 Polarity: Negative

SOLUTION: False

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: I loved this book as a preteen and I loved it, and the sequel "Life with Mother" too. Mr. Day paints an accurate picture of life in the early 1900's for a middle class family. Yes, his father is rude and a bit obnoxious, but watching him is very funny. He loved his wife and family and while he blustered and yelled, they loved him. I enjoyed this book and thought it was great. 
 Polarity: Negative

SOLUTION:
False
