Ex Input:
This book was interesting with great promise. The premise was fascinating but the writer fought with herself throughout. She spent a great deal of time on the flora and the fauna. There was always a paragraph on a bush when a sentence would do, a sentence on a tree when a word would suffice. The characters were well developed. Over all it was a good read.

Ex Output:
Negative

Great American classic that you can get for free on kindle. I was supposed to read this back in high school but wasn't not interested at the time. But now with the benefit of age I can really appreciate it.
