At this point, I would say that I understand some of the rules of football less than I did when I first really started watching the game closely.
IMO, maybe a better option than VAR is just to put more officials on the field, or at least maybe an extra official on each touchline? I think VAR has value, but not in the way that it's being used here.
The other thing that might be done is clarification or revision of some of the offside rules (like someone who doesn't play the ball, but who draws defensive attention because of their position being functionally offside for one) and of some other rules like maybe allowing the keeper to come off their line during the penalty-taker's run-up when trying to stop a penalty.
