Example Input: Review: The musical performances here are quite dull. There is nothing wrong about them except that the musicians seem to be simply doing their job and nothing else. If I had paid good money for this concert in person, I would have been highly disappointed. The video quality is even worse. The DVD is cheap but not cheap enough to justify its purchase. 
 Polarity: Negative
Example Output: True

Example Input: Review: Very well made and solid (heavy). Not the sort of rack you would want to pull on and of your vehicle by yourself very often. If you want a rack where you don't worry about your bikes swinging in the breeze this is it. The rack does fold up so it doesn't stick out the back too badly when the bikes aren't on. The receiver pin tightens to take out the slop between the hitch and the rack. 
 Polarity: Negative
Example Output: False

Example Input: Review: This is my sixth edition, and this book is still a great way to get ready for the season.But the writing has taken a distinct turn toward the serious. The essays and player profiles are still chock full of relevant numbers and piercingly well-considered arguments, but this year they are also somewhat...I really don't want to say it...tedious.What was once a light-hearted romp through some serious baseball thinking is now rather dense and dry. I'll buy again next year, but I hope somebody sends them a keg of Lighten-Up.+ 
 Polarity: Negative
Example Output:
False
