The short attention span of some fans is really quite annoying.
It’s not that. Sometimes the crowd rejects your long-term arc.
E.g. Roman Reigns.
WWE persisted with their long-term arc for Reigns and Lesnar, while almost completely ignoring anyone who caught fire unless it was part of their original plan.
Did fans reject Roman due to a short attention span? No.
Russo is on record with what he would’ve done with Roman Reigns. When he won the Royal Rumble and The Rock came out to boos... he was calling an audible in the headset to have Roman flipping off the crowd and turning heel right then and there, because that’s what someone in that situation would really do.
He probably ends up getting cheered at WM31 because of it and save us from 3 years of stubborn, long-term booking.
Short-term flexibility is important - you can’t assume a compliant audience will always react the way you want them to react.
As for AEW, so far I’ve seen them push Darby Allin due to crowd reactions, so I do think they’re utilising short-term booking principles when appropriate.
AEW say they “listen to the fans”... that means short-term booking, and they’ve delivered on it, thankfully.
Wrestling is a highly dynamic, constantly changing thing.
The wrestling ring is a market place for the audience to choose to buy or not buy situations presented to them.
Long-term booking sounds great in theory, but when overdone it stifles creativity and ignores the market’s response to your product.
