Talent trumps mystique these days. Back in the day you could be a hero and you'd be loved, even if your biggest moves were a big boot and a leg drop. Fans demand more than that today.
Larger than life personalities just don't jive in todays wrestling. It makes me sad. You just can't go out and rock rhinestones and tassles and be awesome. I doubt we'll ever see another Brutus the Barber Beefcake, Jake the Snake Roberts, or Isaac Yankem DDS. Maybe not even another Iron Sheik, and even trying to pull a Yokozuna would be a stretch nowadays.
