As a fan, it's important to embrace the many different styles of wrestling that each guy brings to the table. Not everyone needs to have Bret Hart's technical excellence or Rey Mysterio's high-flying abilities or Brock Lesnar's pure strength to put on an entertaining match.
For some reason though, a proportion of WWE fans tend to equate "prettiness" with "quality." If something looks a little rough around the edges, then too many people don't see the merit.
But historically, some of the WWE's best performers had no use for such fanciness. They didn't whip out hurricanrana's and figure-four leg locks, and very few had any use for showboating with an extended Gorilla Press. No, these guys preferred to get the job done primarily with their fists, feet, and forearms - and just maybe whatever object happens to be laying around at ringside.
Brawlers have been an essential part of WWE's lifeblood since the beginning, and the best of the best have figured out a way to get over with audiences while executing moves that even your drunk uncle could pull off.
These guys are the crème de la crème of the brawling style, and would absolutely beat the hell out of you for saying things like 'crème de la crème'.
