Example Input: I am a fan of Jack Reacher books, but this is the worst one. Usually he doesn't bore me as much with long winded dialog that takes up pages, and this time not even close. The last 20 pages or so were pretty good when it got to actual action. Not recommended.
Example Output: Bad review

Example Input: This case is made of VERY cheap plastic. It broke while I was trying to get it on my ipod. The plastic breaks easily and can be taken off. DO NOT BUY!!!!!
Example Output: Bad review

Example Input: I am a huge fan of the first two seasons, and purchased this one with hopes that it might return to form. Sadly, its not. First off, let me say I'm an open-minded. If I'm ever lucky enough be able to see these shows in live performance, their ability never ceases to amaze me.
Example Output:
Good Review
