It doesn't stop goal celebrations. Sometimes you celebrate and it gets overturned, sometimes you get to celebrate twice, sometimes you get to celebrate because the opposition has had one ruled out. I've celebrated loads of goals that haven't stood for whatever reason. We have played in matches with VAR. Goals were scored, people celebrated. It isn't noticeable that it is even being used in most situations.
Primarily though, football isn't entertainment, it is a sport. The purpose of sport is to find out the winner so the outcome is more important than the spectacle. Entertainment is a byproduct of sport, not the other way round. If it was supposed to be entertainment first then we never would have appointed Tony Pulis.
