Input: Consider Input: I really like Christine Feehan. This book was very dissapointing. The plot had promise. Nicoletta was a sweet heroine. The prose were good, and the medival Italy setting was an interesting change of pace. However, the plot flows like molasses in January. I managed to get half way through before I through the book down and went back to the 'Dark' series.

Output: Negative

Input: Consider Input: I'm sure I would be able to understand the vivid descriptions and symbolism in this book much better, if Hawthorne were not writing in some sort of moon man language. I don't know about the production of narcotics in the 1800's, but I honestly think that Hawthorne wasn't on a natural high if you know what I'm saying.

Output: Negative

Input: Consider Input: The Mothman story is indeed a fascinating one. Unfortunately, the same adjective cannot be applied to "The Mothman Prophecies." John Keel's theories regarding the nature and origin of UFOs in general and Mothman in particular are more bizarre than the phenomena themselves. I was also put off by Mr. Keel's tedious obsession with men (in black) behaving badly.I've given this singularly overrated book two stars, rather than only one, because it does supply some (albeit nowhere near enough) information on the extraordinary occurrences of more than 30 years ago.
Output: Negative
