What is everyone's vote?
An early runner for me is Sting v. Hogan at Starrcade. WCW simultaneously manages to ruin one of the biggest matches in wrestling history and kills the three hottest stars in the business.
Bret Hart comes out of nowhere with zero connection to either Sting or Hogan and assists in a bumblefucked finish that leaves fans scratching their heads and hugely disappointed in a match that could only end one way- with Sting beating Hogan in the center of the ring definitively.
There was 100% no way they could fuck this up. Mathematical impossibility. Sting beats Hogan, crowd goes wild, records get set, drive to bank and cash the checks, and buy a bunch of bulldozers to push the money around.
Couldn't possibly go wrong.
Fast forward 20 years and I'm watching Finn Balor vs Dolph Ziggler.
