I think people expect movies to make sense. If a character dies in the third scene and is alive in the fourth without any explanation, it's bad story telling. If rain falls up instead of down for no reason, that's also jarring. If a man is shipwrecked on an uninhabited island and uses a table saw to build himself a shelter, with no explanation of where the table saw came from or where he plugged it in, that's similarly problematic.
Stories that rely on magic or nonexistent technology to tell a story are fine, as long as the rules governing the magic or technology are applied consistently. Stuff that's just blatantly wrong or contradictory I find distracting. Some people aren't bothered by that, and anything science-fictiony is generally operating far enough outside the realm of ordinary experience that most people won't notice incongruities.
An interesting case is the movie The Wandering Earth, which I watched recently. A plot point relies on unexplained "gravity fluctuations" while attempting a gravity slingshot causing catastrophic failure of a bunch of important machines. This is nonsense, and made it hard for me to take the movie seriously. Later, though, I realized there's a (probably unintentional) sensible interpretation. The machines failed for an unrelated reason, but the world government can't bring themselves to say that they screwed up so they make up a story that doesn't make sense and everyone knows is a lie, but no one is willing to say so because they're afraid to or want to be "good citizens". This could be interpreted as a commentary on modern China (which is where the movie was made), while retaining plausible deniability.
I haven't read Cixin Liu's short story that The Wandering Earth is based on; I don't know if the gravity fluctuations are present in the original or are given a plausible explanation.
