3) Bring back some element of kayfabe, at least try and make it look and seem more believable.
Vince attracted a broader audience in the 90's by "pulling back the curtain" and admitting that pro-wrestling's a work.
It worked because conceding that it's simply another form of "entertainment" removed a lot of the "sting" fans felt from belittling critics who used to dismiss it as something "everyone knows isn't 'real.'"
The rapidly growing fanbase
(with their "new respect" for the business) soon became as/more interested in the backstage aspect as/than the scripted product.
However, that same tactic also became tired and overused - particularly with less and less interesting performers.
The lost novelty and mystique has relegated professional wrestling to an antiquated paradigm.
Just like a magician cannot expose the secrets and then "take them back," there will/can never again be "true" kayfabe, or anything like it.
