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: The main thing I got out of this book was to take note of the difference between a'market' and what an artist thinks a market could be. While the writing is fairly competent, it can not be taken as completely self-serving. It seems to suggest that if you give them enough money they'll keep coming, but they won't. There are some interesting ideas there, but they're scattered amongst the clunky writing.
Example Output: Bad review

Example Input: I own and use a variety of different headsets for work in the real world but this particular device just does not cut it. It's uncomfortable, doesn't have enough power, is very difficult to hear, makes voice recognition really weird & it feels cheap as heck. The best thing about it, aside from its size, are it's battery life. I'd pass on this, get one that actually meets your needs or buy something more expensive so you don't feel like you've thrown away money.
Example Output:
Bad review
