The Rock was made by the wrestling industry, but he cut out before he could give back. it's sort of an unwritten rule that if so many people are going to do the job for you, you eventually give back and make the future stars by laying down for them. Rock hit his peak, did his first big job to Brock Lesnar, and then left. Meanwhile, it amazes me to see how many people who complain about Cena's simplicity are Rock fans.. The Rock was a robot for years, doing the same lines, the same moves, and being Superman just like Cena is today. it's probably because most people were young and impressionable back then, and they associate with the Rock via sentimental value. In other words, they cleaned the Rock's asshole with their tongue, gave him a rimjob, AND reached around and jerked him off while doing it... but hate Cena.
