Some people on WF are impossible to please. These are the kind of guys who think Mila Kunis is just an average looking chick. Everything has to reach GOAT levels before they even consider it worthy of their viewing.
Admittedly it took a bit long to get going, but the middle-end was great.
I thought it was a great promo. Cena actually said something we've never heard before, and that added some interest. The fact that in his mind, Rock didn't beat him and that he beat himself makes it seem as if Cena is coming in stronger this time. He's mentally prepared and won't let Rock's presence shake him.
Rock ultimately one-upping Cena at the end was unnecessary however.
