Like Brexit, VAR was falsely sold as something that would solve all controversy and allow the sport to enter the promised land. It was a complete lie.
Ah, the complaining is part of the sport. What made Maradona's Hand of God so glorious is exactly that. People want to neuter the sport of the human passion, the human debate, the human fallibility, and the human eye physically at the pitch.
Even with VAR we still have the groaning and complaining about human judgement. The difference is now we stop play, we celebrate goals at the wrong times ... or we don't even if we should be, etc. It's turned football into coitus interruptus.
That's because what we all just really want, apparently, is for the sport to become about calculated video game robots playing for pixel-perfect cameras watched by fatasses sitting at home on their couches in front of their TVs. Nobody even needs to be in the stadiums and see actual moving human flesh anymore.
