They really need 2
Mix the dances like some with classical and original Dancing, Not everything must be hip. Hop uh, wacking and whatever the hell that is, they really need to bring back the old school dancing. Because those music are the best good to judge the individual on their movements.
Overall, it's just that they need to change the style of dancing. They need to do better than that. And if I'm correct, I read once Terence Lewis said that there was too much hip-hop.
