Are you sure about that? in America they are all about size, when they had high flyers and technical quick wrestlers on WWE nobody gave them any ovations, in Japan high flyers are popular, in America its weird they just care about the drama and dialogue and look more than the actual wrestling matches, I remember seeing rey mystiero put on one crazy ass fast passed acrobatic show and the audience was dead. I was blown away and amazing saying wow thats dope, but the audience didnt seem to care about it, they just wanted the beef and drama and dialogue when guys confront each other and spend 10 minutes talking trash back and forth.
Not entirely true these days.
Finn Balor, Seth Rollins, Daniel Bryan, AJ Styles, Bobby Roode, to name a few
All smaller than Riddle (Roode might be heavier but the same height), and all extremely popular in the WWE. Fans don't necessarily get up for crazy acrobatic spot-fests (the cruiserweight division in the WWE barely gets reactions most of the time for several reasons), but smaller, more agile, technical wrestlers who can do a good balance of high flying and mat work get fans all hot and bothered these days. Pretty much all really started in the WWE when fans harshly rejected (and still do) Roman Reigns because they decided to push him into the title picture instead of Daniel Bryan. That was like their first big clue that fans wanted the smaller guy who could wrestle really well over the guy who had "the look" but wasn't as skilled. And then there's New Japan Pro Wrestling, which has a ton of those types (Balor and Styles both came to WWE from there), puts on spectacular matches all the time, and is quickly gaining a lot of popularity in the states. I think with fans there are those that mostly care about in-ring talent, those who mostly care about mic skills and personality, and those who care a good deal about both, and these days there are a lot more fans who value the in-ring product than there used to be since in terms of just physical talent, wrestlers are probably better today than ever before. The WWE does try to keep the old mentality alive a bit with guys like Brock, Roman, and Braun Strowman hovering at the top, but compared to the past, the days of the big men are dead. There's still a small amount of "He's too small" sentiment that comes out once in a while in the WWE, but it's pretty minimal. Once Vince is out, I see them transitioning even further away from guys going far because they're big.
And there was even a point where Rey Mysterio was pretty over with the crowd, but yeah, overall he didn't really draw when they had him on top. But even recently there was a lot of positive buzz from fans about the possibility that he might come back to the WWE.
