Ex Input:
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

Ex Output:
Negative


Ex Input:
This is a great book so far. I am a little farther than halfway into it and it is great. Although the writing is a little choppy at times, it is definitely worth it.

Ex Output:
Positive

There is enough product on the mini pads to go over your entire face and neck. The fragrence of step 1 smells good.Overall this product does work. It definately clears up your face. I didn't use this product everyday since I wasn't sure if this was a product that contained 100% natural ingredients.

Ex Output:

Positive
