In alot of ways, the Rock is the perfect professional wrestler. He's good in the ring, and great on the mic. He's an all round entertainer. Probably the best on the mic there ever has been. His character is awsome, and unlike some of his predicessors (ei. Hulk Hogan) he knows how to wrestle. Both is dad (Rocky Johnson) and his grandfather (High Chief Peter Miavia) were good too. I've never seen a movie he's done, but regardless, his true gift is for wrestling.
That being said I don't believe him to be the best ever, or even the best around today.
Sometimes it disturbs me how much I know about pro-wrestling. I've been watching it for over 20yrs. so that's my excuse.
