Probably should just not offer my opinion since I'm a Yank, but the problems with VAR are all a problem with PGMOL refereeing, process, and technology. Every sport played in Yankmerica as well as
our 51st State uses this technology to varying degrees. Hockey has had a good system for a long time and people still complain about the time to get it right on some calls that take 3-5 minutes review. Of course, stoppages are more common in hockey than soccer/football but people will stop complaining about stoppages if the calls are consistently right. The NFL has the review process almost perfected, with an
average review time right around 2 minutes. There are some simple steps for making VAR work, but the issues are not at all technological; the issues are all governance.
