@dale in the end the solution was to do a thing with all the other stars being 5 stars or 4 stars but with a fifth star with just a star outline to show what a lack of a star looked like, then at the end put 5 lack of stars and had to put in text saying Yes We Really Did Get Zero Stars! just in case they tried to complain that we were triyng to hide their zero review as a 5 star review.
They gave a perfect quote too "Theatre for people who hate theatre! I hated it beyond words!"
