Does everyone want a good reason why Alberto Del Rio is so great?
As a heel what did he do? He toned down his in ring work, relying on stomps, kicks, submissions, and the very occasional high spot to keep from being seen as a great wrestler and keeping the crowd from getting behind him. His mic work consisted of repeating that his destiny was to win etc. Essentially trying his best to not be entertaining and pulling it off getting everyone, including the internet to hate him.
As a face he adds more vicious strikes, flashy high spots, and smiles. Then on the mic he entertains the crowd and smiles. Long story short he entertains the crowd and makes us love him.
I will say it once again, Alberto Del Rio has the crowd in the palm of his hand, the charisma and psychology he has is almost impossible to match, maybe surpassed by only Triple H in my opinion. Alberto Del Rio can do it all and he is proving it by turning all of your opinions in a matter of 2 weeks.
In 4 words I will explain why Alberto Del Rio is great. HE WORKED THE INTERNET
