There's a blithe decadence in insisting that the details of movie-making fantasy conform exactly to your expectations. It's also suspicious that the complaint is aimed at mainstream movies, rather than, for example, pornography for a male audience. Would the author want more realism in porn? Should there be more dates in porn? Awkward moments where the conquering male can't decide whether or not to pull his date's chair out for her? An inner monologue wherein he wonders if she's hot enough, chides himself for being so shallow, and then unconvincingly reassures himself that he's not that shallow and he still finds her attractive even though he's in the mood for larger breasts?

Of course not, because porn is fantasy that has as a crucial element the affirmation of male power, validity, and competence. Those elements of "realism" would detract from the purpose of the medium. It's the same with movies. In the climactic scene where the protagonist is on the cusp of capturing the Macguffin, what the plot needs--and what needs therefore to be quickly, visually, and unambiguously communicated to the audience--is that the protagonist or the protagonist's allies have been granted access to the god-like computer system that unlocks the whosywhatsit. "ACCESS GRANTED" does this. Is it realistic? No. Does it matter? Nope! Like an exploding car or a space fighter that banks like an F-16, it communicates to the audience in a way that is immediately recognizable and plausible on a time-scale consistent with the pacing of the action.

Complaining about the lack of realism of coding sequences in movies certainly does not identify you as a "nerd" or "smart person above pop culture." It emphatically identifies you as an unimaginative dork and a boring pedant.
