Example Input: Very easy to use. Only problem is you must remove the battery every time which takes some time. A few pics have already been taken and it keeps on taking. We went kayaking last weekend - took about 20 pictures before turning off camera. Great little camera. I would love an underwater case for it.
Example Output: Good Review

Example Input: I really liked the idea of this product and was so looking forward to it... but when it came in the mail today (well about 10 mins ago) I'm disappointed. First off, there aren't as many stickers in here that were advertised. Second, what does "5" sticker?" Third, my nails look absolutely NOTHING like them in these cute little stickers. The pictures show a different model then what actually arrives at your house. It looks nothing like me.
Example Output: Bad review

Example Input: I love the idea of this book. It really doesn't get much easier than this. It starts out with a very interesting concept. The author spends an entire chapter talking about how all those other book titles can help you be ready to begin writing. If that were true, my mind would immediately go into that book. Unfortunately, once you're in said chapter, it is just as easy to simply skip down (or up) or back when needed.
Example Output:
Good Review
