Frankly Hogan gets less relevant with each passing year. He barely makes any appearances on TV, barely even gets mentioned in passing nowadays. He's alienated a lot of his remaining fans with shitty behaviour. Truthfully even if he'd kept himself clean over the past decade his time has passed. He was last relevant as an active wrestler in what, 2002/2003ish? It's been over 20 years. As Brock Lesnar once said, "party's over, grandpa".
I have to say I was pretty underwhelmed with Cena's first heel promo. I like that he kept his usual theme and attire, and the reasoning behind it was solid. Most of the promo was so basic though. There were a lot of callbacks he could have made or routes he could have gone down to make it interesting, but he just kept repeating "you've all been so awful" - with awful not really being a great choice of word to begin with. It also seemed like a promo being delivered at least 5 or 6 years out of date. Cena has been gradually seeing better crowd reception since around 2017, and people have welcomed him back openly over the past few years. He didn't explain why he waited until people actually did respect him to suddenly turn heel. There is a logic that could be brought in there ("the hypocrisy of fans suddenly cheering for me just because I'd been gone for a while made me sick"), but he just pretended like that acceptance has never happened.
Maybe promos going forward will go into further details and nuance, but for a promo that went on for so long, it didn't feel like he said much that was interesting. Cody calling him a whiny bitch was about right, and I have to say it's not the path I would have gone down. I would have preferred a cocky, arrogant Cena taking real shots at the fans (not just "you're awful" and "you're living your life through me because your life sucks", yawn) rather than a pouty, whining loser.
Although I will say him singling out the kid in the crowd and then the camera showing the kid looking shellshocked was great, lmao. But still, even though it was an okay "I am a heel now" promo, it was just okay to me. Functional, standard, average. I expected more from a guy who must have had plenty of resentment inside him for years over being rejected by the fans and being unable to turn heel thanks to Vince. It could have been an all-timer promo and was instead just a passable one, boosted slightly by the nuclear crowd heat.
I actually thought Punk's promo from the night after the PPV was 1000x better. Calling Cena and Rock bald-headed frauds

Punks's promo felt authentic, like a real guy venting his anger. Cena's felt like a wrestling promo.
