Let just think for a moment without VAR,
How do you feel when your team gets away with an offside goal?
How do you feel when the opponent gets away with an offside goal?
I know I don't like either of those situations and any reasonable person shouldn't. We'd all rather have the call correct in the first place of course, but I think VAR in the current state needs significant improvement.
When done correctly it shouldn't take 5 minutes. They really need to make a call on the pitch and then look for 100% evidence to overturn the call.
I think what VAR has been doing right now is pointing out some of the rules that needs to be modified. Clearly the handball rules need sorting out because they can't get a consistant call when watching a replay but it's less VAR's fault then the rules or understanding of the rules by the officials.
