Example Input: The idea of an individual book on my favorite tv show was really exciting! So when the calendar arrived it came in a timely fashion, and though there is nothing wrong with it, I did anticipate that there would be more than one episode in each month.
Example Output: Good Review

Example Input: I wanted to use the camera with a Nikon D700 and was told that it would work but when i plugged in everything and put batterys into every thing and nothing worked no matter what settings my camera.....DONT BUY.... get an expensive one so u can watch your cam. And as far as quality from another review yes its not HD but good enough for the price of $20. So save up some more money...spend $40 extra on a better one.
Example Output: Bad review

Example Input: I have not finished reading this. All it is, is a book rehash of everything found all along at the Internet. It tells you how to build your own website but does not tell what that means. You can look up tons and more web sites on line free of charge. Save yourself some money and time, dont buy it, borrow if from someone like the library. If she wrote it in 15 pages or even less it would be much better material for you to read.
Example Output:
Bad review
