Example Input: Review: An AC/DC power converter is a very basic item, so I had little doubt that this sub for the expensive Apple original would be effective, though not stylish. Unfortunately, we have had problems. The Powerbook started delivering electrical shocks and inconsistent charging with this adapter, and they got worse when we moved to a country on 240V. I know that the shock problem comes from the Macally adapter because I have another PB and an original Apple power supply, so can do all combinatorial tests. I like Macally and have several of their other products. I probably just got a bum unit but unfortunately cannot deliver a positive review based on previous experience with the company. 
 Polarity: Negative
Example Output: True

Example Input: Review: I specifically got this version of the movie for my husband so he could have the movie on his iphone. The code expired in September and they are still selling it to people as dvd+blu-ray+digital copy. But you cannot get the digital copy because of the expired code. If you wanted the file for itunes like we did, DO NOT BUY!!! 
 Polarity: Negative
Example Output: True

Example Input: Review: Tess of the D'Urbervilles is one of the worst books I have ever read. I read this book in high school, though I am now in college, but don't discount this review because of that. Tess has absolutely no backbone. She pines away for stupid Angel who is more cruel to her than the guy who raped her in many ways. I know women weren't as strong at that time but even so, she is still pathetic. When she tells Angel that she would jump in the river and kill herself for him, I laughed out loud! Tess is a spineless, pathetic excuse for a human being. She needs to take some lessons from Jane Eyre, a hundred times better heroine. Also, Hardy describes the same stupid valley so many times that the book drags on forever and seems like it is never going to end. I disliked all of the characters so much, that it made the book have not one redeeming quality to it. If you want to read a Hardy book, read Mayor of Casterbridge--it is much better!
