A few things on this, the idea that Ric Flair is a reliable narrator is quite hilarious, but aside from that, this idea that Charlotte couldn't say no is ludicrous. Paige was leading a backstage revolt within 6 months of her debut, bit more than just saying no to use of your dead brother in a cheap angle. Vince McMahon infamously loves people who will stand up to him and say no, it's the reason Paige is so prominent, why Punk was so prominent, why the New Day are so prominent now, why the Shield were so prominent etc etc etc…
Aside from that, Ric showed once again how idiotic he is by feeling the need to comment. He's just done a huge amount of damage to his daughters standing in a company where she isn't thought that highly of anyway.
The angle didn't work because it didn't fit the feud, had no build and to be quite frank the Flair family means nothing to current fans, it's not like it's a dynasty, it's one great (possibly greatest) wrestler and his kids, none of which were any good.
