It's funny, the hatred Cena gets reminds me of when I was a kid. My grandpa loved Ric Flair, Dusty Rhodes and Ricky Steamboat, and I was into Hulk Hogan, Warrior and Randy Savage.
I had the action figure, the Hulk Rules shirt and the bandana. Gramps always got in my case saying Hogan was a joke and he wasn't a real wrestler. 20 years later I'm not a fan of Cena but it's the same shit, a limited in-ring performer who appeals to kids via toys, shirts and super human boosts of invincibility during matches.
