he will have a successful career, but he's not the rock.
expect Roman Reigns to be following in those footsteps next, but he also isn't going to the The Rock, there's only one Rock.
that being said modern hollywood does have a lot less jacked up action hero dudes than it did 25-40 years ago, so these former wrestlers who can act a little bit/who have decent comedic timing will get roles.
there's a reason why Batista/Cena have already been more successful actors than Hogan was, they have something.
but The Rock is one of a kind talent.
