This is essentially the argument I use when debating against some of the things you raise in other topics. Enthusiasts can talk at length about how someone is using the wrong gel on a par can and really lose sight of the big picture, entirely misjudging the mood in the public at large.
You're right but you're wrong. To be honest I think you just dont get theatre at all so you seem to get annoyed whenever anyone cares.
The public shouldnt have to care about the specifics, but it all amounts to the experience they get. They wont care about theme park H&S, engineering, business or whatever else either, without realising how much their guest experience relies on it all under the surface.
The public dont consciously care about what kind of light is used, if the sound is at the right level, etc.. of course they dont. If done right, all the work goes into it so that you
don't specifcally notice these things! It's all about the overall effect it makes. That's what really makes the difference between guests coming off underwhelmed or really entertained.
Honestly, a Disney ride could end up just like Duel is now if it was left to rot in the same way. The sets would show up, the timings would be off, illusion not working, the effect gone.. But after a while nobody would know it could be any different and just think "it's ok" until it inevitably gets removed.
Either that or some enthusiastic staff comes in thinking they know how to fix it and you end up with the 'DIY' jobs you see cheapening older UK rides all the time. Or lame fan service changes that miss the wider appeal.
The same attitude plagues theme park operations currently, the idea that anyone can run rides on no effort, so long as no safety rules are broken then job done. There's no reference to high standards anymore. Nobody realises that these things can actually be worked out and solved to massively improve guest experience.
