Kathryn and Jakob were mesmerizing! I also love Ellenore and Russell but they are #3-4 for me... Ryan and Ashleigh should have been gone awhile ago, IMO. They routine was VERY easy and was choreographed that way on purpose, to merely elicit the emotion of a married couple dancing together, blah, blah, blah; there was really nothing challenging about it. Even the lifts were easy. I think Ashleigh has coasted through the competition on the strength of her partners and while she undoubtedly improved, it would be hard for anyone as inferior (in the top 20) as she not to.
Anyway, I think it's clear that Jakob and Kathryn should be in the top 2, with Jakob winning... Russell is my sentimental favorite, mostly because of the joy he expresses when he dances and his tremendous ability to take on whatever is thrown at him and do it VERY well, in spite of lacking training, unlike the others who do have lots of training. Ellenore is my quirky favorite because she is so unique and so good at the same time. Those four dancers are all great in their own right and I wouldn't be upset if any of them won.
