A mega star is someone that transcends wrestling and goes into pop culture, someone my wife or parents may have heard of. I assure you my wife has never heard of Christian. She may know "that guy from Vikings," though. She definitely knows Drax.
Christian is, in ring, my favorite "ace" in WWE history. His year on top in WWECW basically helped me get back into wrestling after I dropped off in 07. I think he's the absolute master of learned psychology in week-to-week TV matches and an evolution of Bret in switching around set moves and spots to create unique narratives that build upon one another. In listening to the Edge and Christian podcast and the questions he'd ask other wrestlers or the conversations he'd have with a guy like Randy Orton, it's obvious that while Edge was far, far more worldly and better read and had broad tastes, that Christian was a wrestling genius savant and the far superior wrestling mind.
Basically, we get what you're saying. We understand the argument you're making. You don't seem to be understanding what we're saying. Instead, you're going out of your way to be flabbergasted.
I hope you're right. I'd love to see Christian get a great paycheck, have some matches against fresh opponents where he's treated with respect and given time, maybe spread some knowledge in a quasi-agent role and help the AEW guys put together interesting matches. That still doesn't mean he's a megastar. Or even a big star.
