Input: Consider 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.

Output: Bad review

Input: Consider Input: This is a very high quality dog food and I found the price by far higher on this one than in stores. Dogs love it, but they are more active when giving it them. It cost me $4.56 per bag here at Amazon, which isn't bad, so even with shipping there may be an incentive for you to try it. It came quickly as usual, just wish Amazon would lower their pricing! Thanks again. Jim W - Arizona USA

Output: Good Review

Input: Consider Input: This thing is worthless. It is not what it says to be. I tried using the power tip and a regular cord - that was worse then nothing. Maybe i got something wrong but I am not happy with it. Waste of money. Do not buy! Save yours for another one.
Output: Bad review
