My experiences with false shows
When you said that something may go wrong, it's highly possible. One night at Epcot, I was seeing Illuminations with my family and it was really windy and people were afraid of getting hit by a shell or something. Fortunately at the end of the show, I believe that nobody was hurt. But I almost got hit by a burnt piece of shell while I was walking towards future world (it missed me by an inch and it wasn't hot at all). Also a few years earlier I think, I was about to watch Fantasmic for the first time and as soon as it was about to start, the sound went nuts and it stalled the show for a few minutes and then the show started. Working on lighting for 4 years in high school and not seeing any shows because of some flaws, it's safe to say that things could go wrong in the theater.
