The kids watch Italian and Spanish football, granted it's a different pace of game but very very few issues or delays since the early days. As others have stated it's not the technology but the interpretation i.e. the officials.
I'm still not a fan but I watched a lot of the rugby WC, and really enjoyed it. So refreshing not to see histrionics from the players and no back chat to the ref. Also, the clarity of the video checks, everyone in the ground and on TV can hear the discussion. Transparency. It works.
Also, excellent system for a ten minute review of yellows to reds when appropriate, the game continues and the player is punished proportionately.
Like with cricket, the two big positives - the audio for fans (ground / back home) and the fact that all the officials are ex-players. When will an ex footballer ever ref or run the lines, or be in VAR studio? Until that changes it will never be as good as it should be.
