Like Kevin ? Will he ever win ?

Hopefully not until after he's had a few terrible dancers that don't take him past week 3. He's due, and it would take them off Anton's hands for a while. One good dancer (not amazing, but good) is not enough to repay him for the years of utter crap he's had to deal with.

He's been very lucky since he made his debut so sorry, but I'm not perturbed he's not won 2/3 of those finals. Let's see how far he gets with a duffer. However, I'm sure his adoring fans will help him out with votes

I think you're missing a word OP.

In terms of pros who've been in the final more than once, KFG is probably the unluckiest. Perhaps it's that he keeps getting decent partners that could take him to the win, but the public are sensibly seeing past the manipulation... Or maybe he's just unlucky.
It's also worth noting that although Camilla Dallerup only reached one final (which she won) she also managed 2 semi finals and a quarter final in her 6 years.

Brendan - 3 finals (series 1, 6 + 11) 1 win
Ian - 2 finals (series 2 + 3) 0 win
Erin - 2 finals (series 2 + 3) 0 win
Lilia - 2 finals (series 3 + 4) 1 win
Flavia - 2 finals (series 5 + 10) 1 win
Vincent - 2 finals (series 6 + 10) 0 win
Artem - 2 finals (series 8 + 11) 1 win
Aliona - 3 finals (series 8, 9 + 13) 2 wins
James - 2 finals (series 8 + 10) 0 win
Pasha - 3 finals (series 9, 10 + 12) 1 win
Kristina - 2 finals (series 9 + 12) 0 win
Kevin - 3 finals (series 11, 12 + 13) 0 win

I consider Kevin very fortunate to have made the final every year, in spite of never yet winning - he's definitely due a dud next year, and I think it might be good for him. He seems a nice guy who would probably work well with an older, less able contestant IMO. It could show him in a different light and then people would probably feel a bit better if he got a contender again a year or two later.
