You’re missing the point about people falling at Harry potter
The people are falling because the production reconstructed the theater to make the aisle mis-shapen and more Potter-like, which resulted in steps that are not properly spaced, and almost force people to lose their balance. Many people have been injured, some with broken bones requiring hospitalizations. This is a flagrant disregard for the safety of the audience. If this occurred in a showcase house (99 seats), the Fire Dept would close the show down. This is outrageous. See how you feel with a couple of broken ribs (that result from a walk down the aisle to a seat in a theater.)
