Any sort of review....or re-refereeing, if you prefer, is contrary to the spirit and interests of football. It makes a mockery of 'play should be continuous'. I would definitely make changes to improve the state of play being continuous...not break it further.
As I have always said, VAR should be an official watching the video feeds, and communicating in real-time with the referee, to contribute to decision making and stop the referee looking a complete mug as a result of a TV angle. It should be equally applied over the course of the match, in every phase of play. Stopping the game for reaons should be avaioded wherever possible, and the laws and their interpretation should be framed with that objective in mind.
At least if the game is to be actually about football. Which is isn't.
In my view stopping the game to scrutinise a small range of incidents is a complete clusterfuck.
