I don't think it's fair to compare AEW to Lucha Underground or Lucha Underground to any wrestling promotion. Lucha Underground was a television show so they had to emphasize the storylines, characters, and outside the ring stuff a lot more.
AEW reminds me of mid to late 90s WCW. More emphasis on wrestling and treating it like a legitimate sport. Jericho is the biggest name on the roster so he'll definitely get the most attention. I can definitely see Scorpio Sky getting a push and becoming the champion down the line.
I do have a problem with spamming finishers, picture in picture during commercials, and too much flippy shyt for my liking. I think they need to add a few Mark Henry, Bradshaw, Kevin Owen, etc types to the roster. Not every wrestler needs to be able to do a moonsault, hurricrana, etc.
They do have me excited though and actually has me looking forward and excited for the next show. I haven't felt like that when it comes to wrestling since 2001.
