Well, I'll be the first to have some balls and admit why I 'hate' Serra (I don't actually hate him, or really anyone for that matter, but strongly dislike). For starters, the guy is a loudmouth. People try to defend that with saying, "He just speaks his mind," like that's some kind of defense. "Hey lady, you're a fat ass. What? I'm just speaking my mind!" "No honey, you're not as hot as you use to be, and you are getting fat. What? I'm just speaking my mind!" "Yes, it is hard to focus on what you're saying with that grotesque pimple on your face. Just speakin' my mind!" That's absolutely no excuse to have to listen to his drivel all night long while I'm trying to enjoy my show.
My next point would be his pathetic little ego trip he's on. The guy beat a bunch of has-been's or never-will-be's on a show, and in turn was able to skip the ENTIRE WW ladder and fight the champ. Look at the guys GSP beat to get a title shot, or the guys Sanchez, Parisyan, or KOS have had to fight to get up in the rankings. Serra wouldn't have lasted through fights like that if he was even able to get through one. On the show, he recognized that (Or at least from what was shown) so he was a bit more low key. Now he thinks he's the hottest thing since sliced bread and he's running his mouth like some kind of veteran champion. Hey Matty, you got your ass absolutely handed to you by Karo Parisyan, Din Thomas, BJ Penn, and Shonie effin' Carter. I'm supposed to believe you're the champ?
Finally would be the little things that just grind on me. Everyone has little things that bug 'em, and it seems like they take those things for Serra and shove 'em right in my face. His constant screaming in the corner, his disgusting mouth (Seriously dude, buy a vocabulary), his hypocrisy - Seriously, you're a "bully," so I'm going to insult you and put you down! Are you kidding me?
Anyways, those are my reasons for not being a big fan of his. I never minded him until he got all this publicity and let it get to his head, but now I'm pretty darn sick of him. Maybe he's a nice guy off camera, but what they're showing of him isn't giving him the best face.
