Players, managers, and fans complain about the inconsistency of refereeing decisions. If the rules are draconian, then the rules should be changed, not VAR.
All VAR is, is a replay of an incident and shows the ref operating it, what to do if there is an issue with it. It's then up to him to advise the ref on the pitch, to implement the rules as they stand at the time, to the incident. And in doing so, provide the consistency that many have been screaming for, for decades.
It doesn't do emotions, it has no regard for big clubs or small clubs, big crowds or six men and a dog attendances, it just presents the facts. Communication and speed of decisions can be improved, but it's still doing the job it's supposed to do.
