It depends on the context, I believe VAR is still pretty far from what it's supposed to be, the initial idea behind it neither can we call it a finished product as such, but there have been progress, it has helped surely certain calls get made correctly and some reversal too be it cards or goals that would have looked legitimate at first glances and vice versal, however, it has taken a bit away from the fun too when there have to be checks for almost every goals and all card-worthy offenses, it takes the flow and tempo pf the game away and that could be a huge advantage for team under immense pressure they get breathing space and try to get them self together. I like the fact plays are always allowed to continue until the ball is out of play before there is a review, but there are still a lot of things to be corrected or improved on in order to make it worthy of the goal it was set out to achieve.
There had always been a camera for every game so I'm not sure how different is the VAR from what we see on NBA or boxing where we see every action being replayed whenever a violation is called.
VAR is completely different with NBA video review, even though they are set out to achieve the same purposes, NBA doesn't review every basket made or every potential goaltending and it's often gotten wrong in certain instances and review are usually made in only certain instances especially with hard (flagrant) and take fouls, and there after each team gets one decision challenging opportunity for the entire game, and after that's gone every refereeing decision are as though there isn't a VAR, you can't any call overturned for or against you if it wasn't called in the first place.
So, my opinion having said all that would be that VAR has been an improvement to football, because it's has always been an eyesore when blatant infringement go the wrong way, because they couldn't have been notice without further review.
