<p>It amused me to no end when the feud between John Cena and Dwayne "The Rock" Johnson got real personal a few years ago. While much of it was obviously scripted, like everything else in the WWE, there was definite tension and real-life animosity there. One of the central sticking points of the feud, which seemed to come directly from Cena's true feelings, was that Johnson had betrayed the WWE and its fans by crossing over into Hollywood and leaving them behind. Cena would constantly say he'd never leave and that the WWE Universe was his life. And yet look at Cena now...The wrestler, and longtime focal point of Vince McMahon's promotion, has been slipping away an awful lot these last few years in order to film other non-wrestling projects.</p>
