I'm willing to give it a chance for a season - it just needs to be consistent. Currently I'm not surprised to see the hate for it, we're getting shafted left and right and only 2 games in.
So far we're the team being screwed by it; but the offside rule and the handball rule seem to be fairly clearly set out for VAR usage - they simply cannot justify now not giving these same decisions against Liverpool/United/whoever. (Although saying that it appears the Premier League are misusing the official IFAB rules on this new handball rule; and according to those written rules Laporte shouldn't have been penalised as he didn't control the ball after it hit his arm (!)).
It's the penalty decision that's the most frustrating, because they cannot be consistent with that; sometimes we'll see them call down and give a penalty, and other times we won't.
For me it should have been implemented slower; starting with the clear cut decisions (e.g. just goals where offside is in question, or where handball is in question), so that we can be eased in to how it will work. Rather than thrusting it into all aspects of the game at once, but hey.
