I think the best way forward with VAR would be for teams to have say 2 challenges a game if the appeal is right they keep the challenge.
Theres so many decisions this season where harsh calls have been made. Every time the ball brushes the arm seems to immediately result in a foul which doesnt really take into consideration the speed, distance and power between the ball and the opponent it strikes. There are also so many inconsistencies of when it is used currently at the last world cup a Colombian player should have been sent off for head butting Henderson and Henderson arguably could have been sent off later in the game for another off the ball incident yet VAR was not used despite replays we all saw.
On last night the referee was ridiculous. The best part of stoppage time was her looking at a screen and waiting for the penalty without adding that time to be added on. That said at 3-0 and with 18 minutes left you shouldn't be drawing that game.
