AEW had a solid chance at the beginning, being a new big promotion with names all over the place and plenty of hype, but the inexperience of Tony has been the biggest enemy of the whole promotion and it killed any real chance AEW had to make it big, people around here love to meme with "cracks are forming" but back when it was first stated it was spot-on and at the current time they are on full display.
Not like it can't turn things around, but with how niche wrestling is nowadays I don't see it happening at all, I think their biggest period yet was that Kenny/Christian feud and then things slowly started to go to shit...with the moment Kenny left being the definitive game changer.
TL;DR: Tony is the problem, horrible booker
