Uhhh, are you serious right now? Have you ever read a review? You're aware that reviews are all opinion based and, therefore, 100% biased?
A guy picks up an album. It is of his favorite all time band. He reviews the album. Of course it comes out in the 90%-100% range. Now an impartial person picks up the same album never before hearing this band or even of them. Writes a review. It comes out 90% - 100%. Whose review is more accurate?
