Great post, Tak.To answer the question - absolutely nothing. The people who love them will love them, the people who hate them will hate them, etc.
For me, reputation has very little to do with medal count. Two of my absolute all time favorites - the Duchesnays and A/P - only won 1 world gold each. Yet I can still remember all their programs, see them clearly in my mind, and remember the excitement and emotion I felt when I watched them skate. For me it's programs rather than medals that makes dancers' reputations.
I was despairing of V/M until this year. With Carmen they have really ascended to that next level and are now FINALLY living up to their potential. This is HANDS DOWN the absolute BEST interpretation of Carmen I have ever seen and will definitely rank as one of my all-time favorite FDs. I am so glad they finally decided to get a real choreographer. Everything in this program belongs - it's an organic whole - it has a very definite POV - all the elements not only fit the program but add to the mood - this should get a 10 for interpretation. My only regret is that they didnt come to WTT - I was so looking forward to seeing this live.
This is the best thing they have ever done and Im so glad they are sticking with the choreographer for next year. And they've specifically said we shouldnt expect Mahler 2.0. They set the bar very high with Carmen, but I am expecting something equally good next year. Whatever medal they win, their reputation is secure.
