I'm not agree with the results. At all.
As for me, the best singer was Alyosha from Ukraine. She was amazing! The diapason of her voice is 4 octaves! Unreal....
And I like guys from Turky, I enjoy their song.
Oh, adding to this, can notice a girl from Azerbaijan. I like her too. The song was rather usual, but her voice - one of the best.
