Orton is an interesting wrestler. He's one of the biggest stars on Smackdown, and yet so many times he feels like just another mid-carder. I can't think of another wrestler on Orton's level that I ever felt this way about.
Hopefully (and probably), the heel turn will fix that problem. It definitely has so far. Orton has been more interesting over the last week since, unsurprisingly, the last time he was heel and a member of the Wyatt Family.
