I'm gonna be that guy, but I wasn't too disappointed with the Rock, because you pretty much know what to expect with him. Catchphrases, talk about genitalia, make an odd reference to get the fans to chant something silly. He did it the entire Cena build up.
I just remember Rock's first promo being epic and then all the others being a slow decline to tonight's terrible attempt. I wonder if the first was just because it was so awesome for him to be back, or if it was really actually good.
