A moment of inspection in the form of metaphor, idiom, and allusion, if you don't particularly mind. Or if you do, but apologies in such a wise, and the hope that the case does not arise again. Without much further preamble, the brief message to convey.
Spectacle should not be performed at the cost of injuring a story's conveyance or internal logic.
A stain glassed window is often a beautiful thing, crafted to impress with eye catching detail and flow by an artisan, and it's wholly worth appreciating where appropriate.
But a stain glassed window should not be used in a submarine, where any open viewing material embedded in the hull poses a potential risk to structural integrity and air tight status, but particularly something meant purely as fanciful decoration. If things begin to go deep, the vessel will be crushed in for want of practical application instead of pretty fluff. It can, one desperately hopes unintentionally, kill the entirety of the necessary mood if done out of place.
Even more so, one should not build a cathedral solely out of stained glass, lest one wish it to break at the first stone in the wind. Strong foundation and solid work to illustrate something more is instead desired.
It is much the same for attempting to wow an audience or a reader, especially if done to the detriment of the plot. As a means of enhancing where appropriate, it (spectacle and drama) often makes some of the most cherished memories associated with something. As a pure force in and of itself , it's puerile, fragile, and often rightfully derided.
There is a time and a place for things, and a matter of propriety. If setting off a nuclear detonation in viewing-and-dust/concussive-force distance *breaks* your story about a clean, cryogenically frozen family torn apart by scientists absconding with the baby to study their genetics, you have written a bad story. The radiation exposure precludes any particular usage, and especially the espoused one, that those scientists would have.
Or attempting to force an ending, such as the oft lamented Reigns campaign in the wrestling world, justified by flash and sparkle and heavy handed fate, but without enough contextual story appreciated by the indulging crowd to actually achieve.
To meet the requirement of at least two possibly-poor examples, another one.
Imagine the big dramatic lights, colors, sounds, powers, fancy dancy philosophical constructs, what have you intended to impress. Now imagine that they are, in fact, cinnamon, and you are attempting to bake for someone. Have you got it in your head? The sprinkling tube with the brown powder, perhaps one you associate with the holidays or family?
In small dashes, it can improve most anything!
Get your pies, your coffee, your ice cream, your cookies, hell, even a few sandwiches or soups, and put in jussst a sprinkle. Little bit. Flavoring.
In big doses, if you instead force your family to eat a bowl full of the stuff straight, you could accidentally kill them. It will taste vile, it will burn, they will cry, and that's even before the adhesive, compact nature of the cellulose in it starts gluing up their mouths and throats. You get very real choking, dry sneezes, wheezing, lung inflammation and asthma attacks. It will hurt someone too have too much, undiluted, and they wouldn't appreciate it even if it didn't.
One hopes the picture is clear enough when going back to the big picture- as fun as over the top can be, it can also be pretty darn disgusting.
To slightly divert from the topic but not entirely culinary metaphor, when you write, remember plot consistency, so that your work does not taste of a sausage burnt on the outside and raw on the inside. Do not reinvent details you don't remember, look it up, care enough about your reader not to impugn their intelligence or their memory. If a character is acting erratically or a plot element does not align because you are trying to force it or can't remember the goal, it will taste bad. Read bad. View bad.
I'm hungry and I consume stories, is what I am telling you.
Again, it isn't something to avoid, by any stretch of the imagination, of course. If you provide enough spirit to the narrative and enough flow to the spectacle, you can make people gloss over some pretty jarring plot details, like a bomb going -into- the Death Star's *exhaust* port at a ninety degree right angle. If they aren't invested, however, or if the event itself removes their immersion from the experience, if it proves jarring- and especially if someone tells you so!- reconsider what you're doing, please.
No one likes crying over spilled milk.
