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: The game is fun, even for 2 years old. BUT - after one year of playing this game, every time I go to turn it on the screen goes blank or comes up with an error message. It's always happens when you need to put in a memory card which takes forever. It also freezes and sometimes don't let us proceed at all. Then I've been having trouble loading games onto my DS. When that happens, they ask why we want to change something.
Example Output: Bad review

Example Input: i bought this item about three weeks ago and its terrible. only worked half time without any problem.
Example Output:
Bad review
