I have been lurking on here for a while and this topic I felt the need to chime in on.
I disagree with this promo on a number of levels.
Some of my favorite shows feature dark humor or tragedy like Its Always Sunny, The League, GoT, South Park, or the Wire, so I am not someone who is overly sensitive to jokes about death/rape/holocaust or whatever.
Having said that, I found the promo distasteful in so much as the Kings return should have just been a heartfelt moment because we had all watched this man nearly die on live television. To turn it into an angle just cheapens real emotion like the crowd and Coles relief that he was alive and joy at his return.
Secondly, the promo largely failed in its goal, which was to make Punk more reviled than Cena. The main event of the night proves this, as the crowd was still pro-Punk and anti-Cena despite Punk threatening to beat King to death again.
To me, the entire situation is a microcosm of what is wrong with Punks heel turn and the WWE as a whole.
It used to be that the fans decided who was face and who was heel. When fans began cheering SCSA over Bret Hart they promptly turned him face and he was wildly successful. When the supposed fan favorite Blue-chipper was being serenaded with chants wishing for his death he was turned heel and became the Rock.
Nowadays, Cena is roundly booed by at least half of the audience who perceives him as a Mary Sue and a smug phony, while Punk is cheered for being entertaining and authentic. Having Cena just smile at the boos and continue to act like a goody two shoes face makes us resent him even more.
PG is not an excuse for shoddy storytelling, and guys can be booked as effective heels in this era, SES Punk, Mark Henry, Undashing Cody Rhodes, and Damien Sandow were all hated because of their character traits and actions.
In comparison, the only avenue that this current incarnation of Punk can turn to to get booed is cheap heat. Up until Hell in a Cell he was a fighting champion, he was still roundly cheered through Night of Champions, and his arguments, that he deserved respect and main event billing, while Cena did not deserve a title shot after failing, were largely correct.
To me, Punks character was largely an audience surrogate saying what was wrong with the WWE, and deserves to be cheered, with much of the audience agreeing.
The WWE has decided to shit all over who the fans decided to cheer for, casuals and smarks, in favor of the status quo, and then have to resort to the cheap heat. However, most people cheering for Punk see this as the transparent bullshit that it is, trying to force the fans to boo who they want them to and not who they want to. The result is largely the same as the 18 seconds bullshit from Wrestlemania; fan refusal to act how they want us to and resentment of the company guy.
