His current gimmick is rather old a dull.
He was better as an insult rapper.
Details, eh?
Ok, when I want to determine whether to boo or cheer a wrestler I look at the WHOLE PACKAGE of a wrestler, not just someone who, not entirely but for the most part, is cheered by kids and women.
By whole package I mean this:
1) MIC SKILLS- Cena does NOT have great skills, and they are like a broken record. Let me explain. Cena start his backstage promo all sullen and calm, like someone ran over his kitten, like he expects people to come up and give the poor guy hug. He then comes to this "relization" in his promo and explains what he is going to do, with a little more volume. He then counters what his opponent said or did to him and volume raised even more. Finally he finishes with a screaming tirade that is all but killed by THE MOST UNORIGINAL CATCHPHRASE for a world Champion... "The Champ is Here".... Nothing original, funny, or exciting about that phrase.
2)Charisma- overall likability based on MIC SKILLS and the ability to tell a story and play to the crowd during a match. Cena LACKS this EXTREMELY important skill and that is another thing that kills his likability for me. He looks boring, and awkward in the ring, like a backyard wrestler. And you can't really tell a GOOD story if you are getting pounded on that much and letting the other guy do the work in the ring.
3)Finisher- The Attitude Adjustment is as lame as the Leg Drop. Nothing much to it. It is a simple body slam. The Stunner will break your jaw, and the Rock Bottom you get forcefully slammed to the canavas with Rock's weight pushing you down.
4)His opponents do 95% of the work, storytelling, and kicking ass in the ring. IT seems like Cena's primary job is to wait until the referee tells both guys in the ring to start wrapping up the match, thus allowing Cena to run through his moves and end the match. No other champion, bot the Rock, bot Stone Cold, not Flair, EVER got beat on THAT much. He's the champion? But can barely muster an effort in a match?
5)the wannabee rapper or thug gimmick is lame and extremely watered down. If he wants to portray a thug, then act like a thug, not some poster child of reformed thugs.
6)His entrance music itself is annoying, and consists, for the most part musically of the same four notes from a trumpet set, over and over again. He needs Jim Johnston to come in a completely change his music.
Thats about it. Hope some of what I said makes sense and clues you in to why I dislike the man.
Sure he does charity work outside the ring, which is great, but in the end that has nothing to do with his actual WORK in the ring.
