Example Input: If you are a fan of this band you really should pick up the Limited Edition cd version as it has 4 live dvd's and 1 music video so all 6 shows can be watched in their entirety. It is worth every penny, I would buy anything they put out! All these Dvds include interviews with members past and present so it's definitely money well spent.
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 bought this cover several years ago and really like it till now. It still looks new but today the leather on the flap came off. There were no tears or anything, just some glue that comes off in one piece. That is why only 2 stars. : -(Maybe that's how they all come off. If you are careful with it, may work for you. Not sure if everyone needs a lifetime warranty.....UPDATE: I contacted customer service at iPearl.
Example Output:
