Ok, before i start I am not bashing Miz fans and I repect him in real life for his dedication to the business.
For me, my main problem with the miz is the complete lack of anything that makes him credible or Intimidating, I know that he is supposed to be a lucky/fluke champion and more on that later. Lets start with his build up, about a year and a half ago, he just stated that he was going to win the US cnampion..no build up or anything. He comes out with new gear, catch phrase, and song..( why does it seem that to be a threat, you have to have short tights?. He wins the title with no real build up. then he has the title for a long time, and has no real good fueds. then the give him the tag titles as if to say " He has to be a threat...look at all of his titles!"
He loses all of those and wins MITB, and then the WWE title. While he has won alot of fluke matches, he has one a decent amount of them clean..and againts people who have much more skills then him, as if to say..."look..he beat good wrestlers...ergo he MUST be crediable..right?" His promo skills are over blown...he has never wowed me and they are boring and predicatable..." talk, lower voice, scream, say really, say something smarky, catch phrase".
Even if you dont like it, it seems that every other champions has something that makes them credible or the excel at..Hogan-size and charisma, Ultimate Warriar-Size and Charisma, Bret Hart-Technical skills, The Rock-Charisma, Stone Cold-Brawling and Charisma, JBL ( a Fluke Champion) Size, Charisma and a STABLE helping him win..Not a NXT rookie and an Announcer. Even Rey has great in-ring abilities.
The Miz isn't big enough to do power moves, isnt a brawler, can do high flying moves, Isn't good a technical moves, isnt athletic enough to so cool "spots", doesnt have an aura of being a bad ass, nor plays mind games (I.E. Roddy Piper, Jake the Snake, Raven, "Cerebel Assassin" HHH). The miz has some mild charisma..and thats it..if he exceled in anyother area, i think that he would be more over. I think that if they gave his push to others, he would be much more over than him.
Sorry for the length, I just wanted to get this out..If you disagree I have not problems with you and would like to read your opinion.
