You might argue that nobody cares about such veracity in a show based on a cartoon and now expanded into a family musical full of color and exuberance - if still wanting for an overarching theatrical reason for being. But if the director Casey Nicholaw, the book writer Chad Beguelin and their cast all were just to pay a little more attention to the importance of committing to the truth of the plot, however familiar, it surely would greatly improve this show. And it would make it easier for us to engage with characters whose romance lacks emotional stakes, not least because it exists in a world without need.
