Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Q: The plot develops nicely then ends abruptly with an unsatisfying ending. It seems to the reader as if the author had reached her contractual page limit and slapped an ending onto the book. A superhuman villian was terminated too easily. The method of capture was not adequately developed. Several promising themes were not followed up by the author, especially the entriquing possibility that through genetic testing Gault's uncle may have been his father or the reason for the military being interested in the investigation. The author took one of the least interesting possibilites and handled it in a below average formulaic manner

A: Negative

Q: I just now purchased on Amazon my third pair of Hi-Tec Men's Altitude IV Boots (over the course of 10 years). I live in Minnesota and have found these boots to be excellent in all types of weather, year-around. In addition to wearing these boots every workday on my warehouse job, I do a lot of weekend hiking, camping and exploring of the North Woods and have never been disappointed with these boot's performance. When worn (and sized) for a good pair of extra cushioned wool socks (I buy Smartwool Trekkers Series), these boots are warm enough for shoveling snow and are also comfortable and cool enough for summer wear. It is a perfect light, all around utility boot and I highly recommend them. They are the only boots I have ever literally worn out (they never failed due to workmanship or materials). I just replace the shoestrings with a good quality boot lace and they "keep on running"!!

Positive
