Example Input: I purchased this MP3 player as a Christmas gift for our daughter only to find out on Christmas Day that is not compatible without our computer despite every update available. While we could see the preloaded video and it is very clear and bright, we were never able to upload any music. My husband (who is computer wizard) spent 12 hours trying to get this thing to work, but without any success. Next time we'll buy an IPod.
Example Output: Negative

Example Input: What a pleasure to read such a high-quality book... It introduces each of the islands in a colorful and vivid way. The book includes many pictures, and provides a fine insight into the culture and character of the islands and touches on history, people, travel, activities, sights, nature, and a lot more.However, if you are looking for a book with accurate travel information, e.g. hotels, restaurants, prices/dates, how to get there, etc., this book is on the weaker side. Use it together with the Frommer's Caribbean guide for a combination that is hard to beat. Despite this weakness, it's still a five star on my bookshelf.
Example Output: Positive

Example Input: This performance is pure garbage. Unfortunately I was at this pathetic show. The audience was mostly old geezers who were there to watch a group of other geriatric has-beens. The sound was awful, their performance of West Side Story was ridiculous, and their hatred for America was sad. Halfway through the show, the singer was having serious trouble hauling his fat *ss around the stage. He sounded like an exhausted pig, gorging himself at the trough. It was bad enough that they would embarrass themselves by performing in front of people, but they actually recorded their disaster. Now they think they can sell this crap??
Example Output:
Negative
