Example Input: The poster has great graphics and looks great. Good size image to hang in your dorm room. It also arrived sooner then expected so i will order from Poster Revolution again. UPDATE....still no problem with poster! Great value!
Example Output: Good Review

Example Input: This camera was not very user-friendly at all. The first time I went to use it the shutter button got stuck. We could hear and see things flash on screen, but no picture. After spending almost a half hour trying everything, we finally gave up because this is too big of a headache for me. Now I'm just going to get a point-and-shoot type without all the complicated settings. My advice, do what everyone else does.
Example Output: Bad review

Example Input: I'm sorry but I don't understand how anybody could give this book a five star review unless they have actually done it. A lot of people loved or at least didn't mind reading it.
Example Output:
Bad review
