Lol, the problem isn't who they have...
...it's how they are used
Some exciting angles, new gimmicks, a few shocks - a good feud can make even someone as bad as Mark Henry look intresting and get cheered
Was Austin great or was he just in unbelievably awesome angles? McMahon v Austin - how could u fail?
Kane can't wrestle - a cheap mask and a good opponent and he's got a zillion fans
I think its more about someone who can carry a company on their back. Kane & Mark Henry don't have that ability or charisma to do that.
Austin was just that great. He had it all. As did the Rock, Kurt Angle etc
I understand you can create champions with the right angle... but we are talking superstars with everything that can be as big as guys like Austin, Rock, Hogan & Bret... those four are what all others are marked against IMO
