The only time slow motion replays should be used is in determining contact. Outside of that they should play absolutely no part in VAR decisions.
The number of times VAR has made the wrong decision because they have looked at an incident at 1/20th speed and decided that the player intentionally did something that was completely accidental or decided that (like in Balbuenas case) the contact was sustained and nasty is beyond a joke. When you see the Balbuena one in real time its all over in a flash. In slow mo it looks like he kicks the ball, follows through intentionally and perfectly and continuously rakes down the other guys calf.
Does anyone really think VAR has been good for football at this point. Goals be chalked off due to offsides measured in mm, red cards being given for nothing, goals chalked off because of a minor, debatable foul 20s earlier.
I don't honestly care that much about the "we can't celebrate anymore" part. I care that despite VAR supposedly catching mistakes, its causing just as many as it solves and things that are clear to every man and his dog are being ignored by referees.
