"It wasn't just about his dance moves, it was about the entire performance," said JC Chasez, 32, a judge on the MTV street dance-competition series "America's Best Dance Crew" and former member of the boy band 'N Sync, who sang and danced alongside Timberlake.

"He's one of the first people in pop music to really take the theatrics to such a scale, incorporated with the choreography. ... Now, it's kind of being viewed as that's what every kind of pop artist does now," said Chasez, who grew up "running around, singing 'Beat It' and 'Billie Jean.'"

He added, "And everywhere I stepped, the floor was supposed to light up in front of me." [source]
