Rock/Cena feud sucked and it was hard to watch cause they were doing this thing were Rock was an outsider Hollywood actor, (guy's an wrestling Icon, shouldn't of been trying to make him an outsider) while Cena was the great white knight, protecter of the WWE. As Starbuck says, it was more Dwayne/John, than Rock/Cena. People might be confused by that but there is a difference.
But at the end of the day it has done 1,217,000 so far....highest grossing wrestling event in the history of the business. It was a massively successful, and that was what WWE wanted.
