Cena is too melodramatic on the mic at best. And like the Rock before him, he tends to fall back to insults to get the crowd into his promos.
This will make me an enemy of a lot of people, but the Rock was a severly overrated mic worker. He was average at best. I don't want or need sexual puns and humour, or the insults. I want actual substance in a promo, not style and fluff.
