An eagle-eyed viewer might be able to see the wires. A pedant might be able to see the wires. But I think if you're looking at the wires you're ignoring the story. If you go to a puppet show you can see the wires. But it's about the puppets, it's not about the string. If you go to a Punch and Judy show and you're only watching the wires, you're a freak.
Samuel Taylor Coleridge, the poet and author, called drama "that willing suspension of disbelief for the moment, which constitutes poetic faith ..."
Any creative endeavor, certainly any written creative endeavor, is only successful to the extent that the audience offers this willing suspension as they read, listen, or watch.
An author's work, in other words, does not
have to be realistic, only believable and internally consistent (see
Magic A Is Magic A). When the author pushes the audience too far, the work fails. As far as science fiction is concerned, viewers are usually willing to go along with
creative explanations unless the show tries to use real science, at which point it's fair game, though this is because Science Fiction is just that: Science
FICTION. Attempting to use actual science to explain something you made up removes the story from it's own fantasy universe and places it in the context of reality. That's why
people don't criticize your wormhole travel system or
how a shrinking potion doesn't violate the laws of matter conservation. Suspension of disbelief can be broken even in science fiction when a show breaks its own established laws or places said laws outside of fiction.
A common way of putting this is "You can ask an audience to believe the impossible, but not the improbable." For example, people will accept that
the Grand Mage can teleport across the world, or that
the spaceship has technology that makes it completely invisible without rendering its own sensors blind, but they won't accept that the ferocious carnivore
just happened to have a heart attack and die right before it attacked the main character, or that
the hacker guessed his enemy's password on the first try just by typing random letters, at least without
some prior detail justifying it or one of the Rules listed below coming into play. What is in
Real Life impossible just has to be made the norm in the setting and kept consistent.
Most action movies push this trope almost to the breaking point; for the sake of action, the heroes can do virtually
anything, given enough
Phlebotinum.
As always, the
Rule Of Cool,
Rule of Cute,
Rule of Drama,
Rule of Funny, and
Rule of Scary override nearly all other considerations. When the audience's disbelief, which was suspended during the show, gets reinstated some time afterward, what you get is
Fridge Logic.
The
MST3K Mantra is an exhortation to reinstate your
Willing Suspension of Disbelief even if it's been broken, because "it's just a show".
Incidentally this is one of the more controversial elements of, believe it or not,
Professional Wrestling, and is heavily tied to
Kayfabe.
