Of all the world-wide sports which operate some form of video assistance it's only football, and my experience of VAR only applies to the Englsih game, which seems to have made a complete buggeration of it. And I think that has been down to keeping the system cloaked in smoke 'n mist. Had they had a transparent system from Day One where everyone, whether in the stadia or at home in front of the telly, were privvy to the deliberations we wouldn't be in the situation where clubs are debating whether to maintain it or bin it! It is a clear indictment of how the game is governed and arbitrated - extremely badly.
