VAR has just moved the goalposts a bit. Rather than getting 30 wrong decisions a season there are now maybe 10. And some waiting around.
Fans will always moan about something. If VAR is not in their favour they will moan about it, but they never complain when it is.
I think on balance it is good for the game. But maybe they should introduce some sort of time limit on how long a VAR review can take place. For example, if they can't make a decision in 2 minutes then the original decision stands.
The problem is there is huge pressure on them to get the decision right, and that means they often take a long time to make a decision to be really careful.
There are also some really awful rules in the game that need to be tidied up. Tidy up the bad rules and the VAR decisions get better. Rules should be objective not subjective.
The whole process is in its infancy and is going to take time to develop and work through. It should get better over time.
