It's fair to say that the world of pro wrestling has never seen anything like John Cena, as far as crowd reactions are concerned. There really is no "in between" when it comes to the way the WWE Universe views him. His fans are as loyal, and as vocal, as they get, and they will cheer for him to the point that your ear drums hurt when you're in the building. His detractors are also as vocal as it gets, and they aren't afraid to let you know how much they dislike him and everything about him. That combines to make for some very memorable crowd reactions, whether you're at a house show, a television taping, or a pay-per-view. However, whether you love him or you hate him, you should be someone that respects the hell out of Cena for what he brings to the table, and for what he does for the business. You can knock him for many things, but he doesn't get anywhere near the level of "props" that he deserves. This article will look at ten reasons why each and every person reading these words should admire both John Cena, the wrestler, and John Cena, the man, even if you don't have any intention of watching ten consecutive hours of his matches.
