Mike,
Your impression of WFW is valid, for you, and I don't doubt that there are others who feel the same way. What is also valid is that your impression, and that of some others, is not the same impression held by a much greater majority of people, ergo, WFW always hovers in the top range of great U.S. golf courses.
Is there a 'great' golf course anywhere that doesn't have some deficiency, as noted by someone at sometime or other? The answer to that is 'no'.....and the thing to remember is that these highly regarded and slightly flawed courses have other attributes that score A+'s and that more than makes up for any perceived blemish.
Another thing that always stands out, and I mentioned earlier, is the eclectic nature of what makes it into the stratosphere of the very best. That, in and of itself, says to me that subjectivity is only a part of the equation, and objectivity is more important than many people care to believe.
In other words, quality is quality and mediocrity is mediocrity, there is no long term way to disguise either, so a WFW may not be your cup of tee but it surely hasn't proven itself to be mediocre over time, has it.
