All rankings at best are general guides because each of us is unique, and we each will have a different weighting of the various factors used in any quasi-quantitative ranking. This is one reason the wine rankings are so absurd. A lot of those "100 point" wines would taste awful to most people, especially if quaffed short of 25 years of aging. Your own tastes likely are just fine with some 87 point wine, and in fact, the difference between 87 and 91 points is very slight. The rating doesn't even go below 50, and you never see a wine rated below about 83 or so (in my life).
So, nearly all wines in the $10-$200 range rate between about 88 and about 92. Yay. And some of the points are for things like clarity which may not matter to you, at all.
