I don't mind him as either heel or face (he was heelish during the MITB 2011 angle, though people still gave him sympathy when Triple H told him he was relived of duty), but I think a huge run in an on-screen storyline that stretches over months or whatever has already run it's course as it relates to Vince. I don't even want to think about Steph on TV, with her terrible acting most of the time.
I don't care to see Vince on TV at all unless it's in small doses like he does nowadays. Yeah, he was at one time one of the most hated ever, but you could argue even then that he didn't 'create a new star.' Austin was already mega popular, plus Vince was a heat magnet because of what he did to Bret Hart in real life (which was well publicized) and the novelty of seeing Vince McMahon as a heel character on-screen. It wouldn't have the same effect on business nowadays like it did with Austin.
