I've said it a hundred times before but VAR for subjective decisions is a complete waste of time. There is and always has been clear drawbacks to VAR - it takes up time, supporters (particularly in the stadium) don't know what's going on and can kill the emotion of scoring a goal etc. The only reason for tolerating those drawbacks is if we're getting a lot more accurate and consistent decisions but we're not.
The number of correct decisions probably has increased slightly but not enough to put up with all the rubbish you get with VAR. In terms of consistency things are as bad as ever, in fact from a supporters point of view it's probably more frustrating now because there's no excuse for the inconsistent decisions with VAR.
The only way VAR can be used for subjective decisions is if they forget about this clear and obvious line. Just accept that the qualified official watching an incident 5 times in slow motion is better placed to make a decision than the on-field ref. Telling them that it must be clearly and obviously wrong just causes confusion and is what has resulted in 3 absolutely shocking decisions in the first 4 rounds of the season. Every football fan, let alone qualified official could have told you that Wolves should have had a penalty, Mac Allister shouldn't have been sent off and City's goal was offside but ask them whether it's clearly a penalty, clearly not a red card and clearly offside and you're opening yourself up for stupid answers.
