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 machine is really good, but not without some problems. While the noise it makes does a lot to mask other noises, our cats definitely do enjoy this thing. It also helps keep them calm, which in turn, brings us much peace of mind. However, sometimes you need your hands free for something else -- like getting the cat out from between the mattresses.
Example Output: Good Review

Example Input: Enjoyed the series. Can't wait for my next adventure with Robert Duvall.
Example Output:
Good Review
