The problem with French wines, in fact the problem with nearly all old-world wines (with the exception of Italy) is that they insist on using traditional grape varieties and using the traditional techniques and their vineyards are now so old and their soil, so played out that you'd be forgiven for thinking French wine was musty/bland, especially now you can get such intensely rich and flavoursome wines from the new-world.
French wines require a longer maturation process and you need to leave them to breathe longer before drinking and wine snobs will insist that this brings out subtleties that new-world wines do not have yet it can be equally argued that the French are too arrogant to consider that anyone could possibly make a superior wine to them.
Ultimately, a wine is only as good as the person drinking it, deems it to be and personally I really cannot stomach the vast majority of old-world wines anymore.
I adore Champagne and I love Italian reds (you cannot go wrong with a Montepulciano) but I find French wine in general to be bland and musty and I find Spanish wine to be ridiculously acidic (I lived there for a while)
New-world wines however are so vibrant and fresh and rich that I just can't go back. Australia, Chile, Argentina, New Zealand, California...they make wines that 300 years ago, would have been applauded in France but they're considered lower-class because the French say so (that's it in a nutshell)
