It will work right in the end, if it helps make the right decisions is that not a good thing? Fans have been moaning about wrong decisions for years. Yes there has still been a few questionable decisions but people forgotten all the ones it has helped to make right, that's what people wanted after all or perhaps people need to accept that referees are human and will always make mistakes as long as they are genuine honest ones what more can you ask for, it is such a difficult job, if you accept things will never be perfect and you take the tough with the smooth and by the law of averages things even out overtime, then there will be no need for VAR but as long as people clamour for absolute perfection the search will go on.
