I mean, I'm not going to complain about Charlotte Flair in that, even though people could argue "She gets her spot for being Ric Flair's daughter," she is still incredibly talented and improved as a babyface compared to her first run as one. But people love Becky. It may be a stretch to compare her to someone else, but generally, she is the person who has been incredibly talented, but aside from one moment of brilliance, has been stuck in the women's midcard and I am sure many people are craving for her to get time in the spotlight once again. Plus, her personality is genuinely lovable and she was an amazing babyface. The decision to turn her, may "freshen" her up, but it was a risk since it would be hard to get the crowd to turn against her.
I think either they could have had Charlotte turn heel, especially if the rumours are true of her facing Rhonda at Mania are true, and kept Becky as a babyface. Or at the very least, with her promo on the following Tuesday, present her as more of a tweener, be mad at Charlotte driving her to do it, rather than say the crowd who were supporting her were not, say that "Fan support hasn't got her anywhere." That way she isn't lying, and it still is an attempt to push the crowd against her because her character is so obsessed with getting that top spot, she is shunning those who support her simply because it hasn't helped her much, and if it doesn't, then let them cheer, just Becky doesn't want to play to them. It is especially a shame since she executed her lines well in the promo, just what she said didn't work with the crowd reaction.
But hey WWE, good luck in working with this, it won't be easy.
