For me it's shit because it is not VAR, it's VR. The actual ref has no control, as what he decides is then overturned by some bloke 100 miles away.
VAR should only be used if the ref legitimately needs help or he's made a blatant error. Not for over analysing every tackle, foul, offside call and goal.
Last night the ref actually asked "What for?" when he was told VAR had seen something. It's to invasive.
