It is kind of funny to me, people talk about letting the officials officiate the game… they still are but they’re still getting it wrong with VAR and it is hardly the systems fault that someone looks at a foul or an offside and still doesn’t get it right. Going back doesn’t change much, people will still not like referees decisions and they will still cost teams dearly.
Statistically though it does technically reduce the mistakes, the issue is that they even still make them and in many of those cases they weren’t even on subjective ones.
My personal hangup with VAR is around the rule that contact = foul and if they show a freeze frame or a slow mo, it removes the context altogether.
I don’t think anything will ever stop people not liking decisions or consistency because there will always be subjective ones and people will always remember the bad ones especially against their own teams. But again that happened with general refereeing, people remember the hand of god, the Lampard goal against Germany and the Henry handball against Ireland. VAR would arguably have caught all those.
