I wouldn't be too concerned. I had this wine approximately 18 months ago in a Bordeaux-focused blind tasting I hosted for 10 of my friends. It was the clear winner among a respectable set of grand crus that included 1997 Lafite Rothschild, 1995 Lafon Rochet & others I don't remeber. Unlike what you describe, the wine had a lot of fruit and complexity.
It may be that you had an off bottle, as it is highly unlikely such a young wine would be in decline after only 7 years of age. My experience with Clerc Milon is that it is drinkable soon after release and rarely enters into a dumb phase.
I have another 7 bottles in my EuroCave at 55 degrees waiting to be consumed. I strongly recommend this wine, although the 95 WS pts may be a stretch by 2-3 points.
