Oh Rock, you can make all the shitty kid's movies you want. You're just delaying the inevitable. One day sooner or later you will have to face John Cena in that ring... and lose.
I like to think that if Rock vs Cena ever happened, the fans would turn on the storyline and boo Cena, the more fragile and overinflated face, just like they booed The Rock when he faced Hogan.
I'm working on the CGI effects for this movie. I'm going to see my name on a screen, five feet long and luminous =D
I just assumed it was sillyness, but after seeing the trailer, y'know, it might not be that bad...
