That is where you are wrong. A reviewers duty is to give the reader an unbiased view of various aspects of said item. The gameplay, features, what-have-you, are what add up the points. Then usually at the end the reviewer gives you their 'opinion' which should count for very little in the scoring. Though there are admittedly a few sites who score solely on their opinions, or how much money they got (IGN, GSi, GameSpot).
