I agree. I hate the Character, but respect the man. With that said, I REALLY want that heel turn we've all been hoping for.
Sadly though, not sure Vince has the man parts to do so anymore. Instead, we get Reigns shoved down our throat.
I think people want a heel turn just because, but I don't see a heel John Cena being that interesting. When Hogan did it, he kinda just lifted the veil between his character and his self, and performed as his self. Not sure that works for Cena.
Reigns on the other hand should do a heel turn. Literally all they have to do, is have Triple H help in win the title and come out and say, we know better than the fans, this is our guy, always has been our guy and there's nothing you can do about it. That would create a ton of heat
