I think VAR can be effective and improve the game for the fans, as it did in the Euros, but in the EPL its application seems to be a over the place - its obvious that this season there is a directive to allow for more physical play, but some really obvious stuff is being ignored.
I also think the offside rule needs updating, because the level of detailed measurement provided by VAR wasn't available when the rule was written. Maybe offsides should be measured by the torso, or shoulders, but when goals are being chalked off because a toe, or finger is offside, its not what the rule is intended for.
