Ex 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.

Ex Output:
Negative


Ex Input:
I bought these. After two uses (the first being a french vanilla cake, and the second fudge brownies), they stained from the brownie batter and will not come clean. I figured these would be better quality, since they ARE kitchen aid.

Ex Output:
Negative


Ex Input:
I hadn't read this since I was a teenager. I had forgotten what an excellent writer and fantastic mind Isaac Asimov was. It was refreshing to see character and idea development that kept my interest and actually made me think. Read this and enjoy all Asimov was to the Science Fiction genre.

Ex Output:

Positive
