I get it from the standpoint of a business decision. Vince is basically saying "run me my money" and from that POV I can't be mad at him. He's creating revenue for his company and giving the audience they're specifically catering to for this event what they want so on that level it makes sense.
HOWEVER, as a regular, deregular fan...this sucks, for me. Even if I get past the fact that these dudes are all washed, even if I overlook the fact that Taker has (at best) a half decent five minutes in him, even if I let them slide on being almost 20 years too late...On a personal note this makes me cringe b/c HBK was one of the very few guys who retired in a way that added to, instead of damaged, his legacy. I never wanted to see him come back b/c his retirement was honestly a near perfect blueprint for how it *should* be done. Seeing him come back for what amounts to an ego stroke for HHH and a cash grab for Vince is disappointing.
