I'm going to push back on this: Mopey Emo Bayley was an entertaining and, more importantly, necessary part of the evolution of her character. Going all the way back to her time as Davina Rose, on the indies, you can't go straight from always-positive, Super White Meat Babyface™ to goofy heel, without there being some kind of transition period. Something had to break inside of Bayley, to make her turn heel, and her emo phase was an important part of illustrating that.
