Did you not see the penalty that Australia got yesterday? Never a penalty in a million years I'm afraid. A ball hitting someone's arm is not an automatic penalty. There has to be intent to handle the ball, so how you can intentionally commit hand ball when you have your back to it is beyond me.
There were also the two (arguably three) penalties that England should have had which the VAR officials contrived to deem not fouls. And the blatant push by the Swiss player while scoring the goal against Brazil that was not disallowed by VAR.
So yeah, I think there is 'bad use' of VAR.
