Input: Consider Input: It was interesting to read The Foxes of Harrow again, as a "senior citizen, since I was only in my early teens the first time I read...and enjoyed...the book. It is quite sensual, considering the year it was written. It has held up fine during the years. I probably understood the nuances better as an adult than as a teenager. Frank Yerby was a brilliant writer, and in this book he presents a balanced view of what white slave owners and their slaves faced during that pre-civil war era. I couldn't help comparing it with Gone With the Wind as I read it.

Output: Positive

Input: Consider Input: Nice critic about inquisition times combined with a great introduction to small gods concept for those not familiar with it. Makes you think about faith while it makes you laugh about everything. If I had not read better Pratchett's books, I would have rated this with a five

Output: Positive

Input: Consider Input: It only lasted for less than 3 months then there was 2 holes that I fixed but still there was a leak somewhere and eventually I just threw it away. I don't recommend this air mattress.
Output: Negative
