How do you know that's what happened? I know it's all a part of the story and shit, but really?
Ziggler pretty obviously adds shit to his character; same with Cena (I believe he is who he is on TV for the most part). I mean seriously, just because guys aren't acting like white trash hooligans and cussing and saying shit that doesn't make sense doesn't mean that they aren't putting their own stamp on things.
Also, if you think Vince wanted Rock to keep getting booed, you're nuts. Scott Hall once said that he told vince "if you want me to be GI Joe, I'll be the best GI Joe", that's an OLD SCHOOL mindset. You take what they give you and you try your best to make it work.
Also, as far as the "you can have a talented guy with a bad gimmick and it'll fail" no you can't. that's why he's talented. Golddust is a pretty damn hard gimmick, it works. Rock and Austin were extremely talented and evolved their characters into something that worked. You read the audience.
It blows my mind how many posters on here act like they know vince mcmahon, they act like they know what happened in the 80s and 90s and what happens now, and they knew vince back then. You didn't know shit. If anything, I bet Vince was more of a hardass back in the day than he is now because back then, it wasn't publicly traded and you can get away with being a ******** more in those situations. Plus it's not at all accepted in really any workplace to be utilitarian about things. You have to care about your workers' feelings, even in wrestling.
Something else to consider, look at how young the WWE roster is compared to how it used to be. Regardless of what ****** smarks thing, 25 is not a wrestler's prime. Sometime in the early to mid 30s is their peak. Wrestling is so mental. You have to be comfortable in the ring and on the mic and then you can stretch and do character work and stuff. When you've only been wrestling for 5 years, you have to remember your spots, you don't have the brain space to think "what would my character do?"
Prime example, Ted Dibaise. Great athlete, great look, great moves, shitty wrestler. Looks like he's always thinking about his next spot. Doesn't look natural in the ring and certainly doesn't look like his character. Kofi looks the same way when he's on the mic. Then look at CM Punk, EVERYTHING he does is in character. Same with Cena, and now Ziggler is getting there.
