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: It's cute and nice but too big for a toddler.
Example Output: Good Review

Example Input: The book is good in that it focuses on all the facets of being an artist. Great ideas, helpful tips, and simple but thorough explanations. Just one complaint - It wasn't even proof read! There are words spelled correctly throughout the entire book. However, the formatting from page to "page" makes very little sense. Example: I am writing this letter by Page 5 then next paragraph, two different text sections have been inserted before me with no break between. What a pain in the neck.
Example Output:
Bad review
