just because you are the best at something does not means that you will win.....that is the nature of this sport. I love William Pino and his ease and grace. He makes things look effortless, which is what we all aim to achieve.
I looked at all videos, What I find with Mirko and Alissa is that they to me IMO dont have an emotional connection and if you saw some of their last dancing they did they were disconnected with each other. He may be very good at executing and leading but to sell it emotionally he lacks IMO. I admire his technique.
Not that I think you have to be in love to have that connection as I have seen small snippets of Allissa with her beau Angelo and that yet looks to have a true connection.
Remember that judges only have such a small time to make that decision and the differences between them all may have only been 1 point.
It is like the three tenors which is the better one depends on personal taste.
