I think you might need to research what charisma is. Blank, vacuous stares into the crowd is not charisma. Even Benoit had more charisma than Orton. Shit mic worker, average look. One face for all occasions.
I think you need to research what charisma is:
[kuh-riz-muh] Show IPA

Theology . a divinely conferred gift or power.
a spiritual power or personal quality that gives an individual influence or authority over large numbers of people.
the special virtue of an office, function, position, etc., that confers or is thought to confer on the person holding it an unusual ability for leadership, worthiness of veneration, or the like.
According the definition , it is the ability to have influence over a large number of people, which in this case, is the WWE Universe. Every time Orton comes out, he gets huge pops and is constantly cheered. People love him and that is because of his charisma. People want to see him kick ass even if you don't and are drawn to him due to the charisma he possesses.
