So were Ric Flair's matches. Same flip over the turnbuckle, duck clothesline, climb top rope, get thrown off it. At some point he gets on his knees, then screams "NO! NO! NO!" followed by low blow, ect.
Same can be said for Hogan. Lesnar matches are all the same, too.
I think people more hate Cena's clean good guy image and the fact he's been shoved down fans throats a ton.
