I'm fine with The Rock appearing regularly and just being The Rock, I'm pretty sure he'll even win the title and I'm not that bothered... As long as his presence actually has some benefit apart from more goddamn, motherfucking revenue building stunts for WWE and a paycheck for Dwayne. I want that hectic schedule to be put to good use, to see how they would try to blend modern Rock into today's roster for an active couple of months, to have match-ups with interesting opponents and that he can actually rub off on someone younger and get them over.
A good booker will secure a huge name like The Rock and make that nostalgia dollar. A better booker will consider the ways in which he can be used. I mean, Rock could lose to Tensai next week and he'll still be The bloody Rock. Nothing you could do to him would put a dent in his reputation. The only risk WWE are conceivbly taking by having the Rock show up and do something more complex than making jokes, is that they might not make as much money from it.
But hey, some people just wanna see Rocky show up every now and then, raise the eyebrow and hear the fans go crazy and far be it for me to tell them they are wrong. But if you're content to have one of your all time favourites show up just to repeat the same catchphrases, mock his contenders, take what he wants and not really try anything different... Well, I'm reminded of Super Mario nowadays. Or how about The Undertaker? Someone who - while still capable given the right opponent to work with - just keeps hanging around because WWE are dependant and the fans seem almost afraid to let him bloody go. As a result, his matches (or at least the hype) hardly have the weight they used to.
In any other storytelling medium, when an old or major character sticks around only to appease the audience and not really to drive the narrative or strengthen other characters, its often known as fan service. Fine in small doses, but once it becomes the norm everything around it starts to get stale.
Certainly the sold-out Raw justifies The Rock's presence, but the audience asking for a bit more than that, for things that don't just benefit The Rock, is not selfish or entitlement. Yes he has a heavy shedule lined up, but that's what he signed up for and that's what he's being fucking payed for! If you're fine with The Rock half-arsing it and eating all the pies, then why do we even have him around?
