Review: Easy product to install. No fuss. Plug it in. It is out of sight behind a couch. I am satisfied. 
 Polarity: Positive
Solution: True
Reason: Customer is satisfied with the product. Therefore, it has positive polarity.

I couldn't even finish it and gave it away. The movie didn't follow the book at all, but at least there was a thread of a storyline to follow. 
 Polarity: Negative
