At least you can kind of explain that one away as a crime of passion, but lazy drama falls back on this all the time. There's an entire CSI: NY episode about an injured character having nothing better to do than stare into other apartments mere feet from his own. Yet despite being able to make direct eye contact with his neighbor, one man has no problem plotting a chemical weapon attack with his blinds wide open. It's Rear Window for morons.
The show You is about a stalker, and while we don't mean to blame the victim, the object of his obsession doesn't use curtains at any point in the entire series. She walks around in a towel after showering, changes clothes, and even has sex without closing any blinds. She can afford to buy a new bed after hers breaks, but never thinks to invest in basic privacy. And all the while, right across the street, a dude casually watches through her gigantic windows.
This lack of basic common sense also has a proud legacy in comedy, thanks to the "classic" gag of horny dudes glimpsing an unsuspecting woman. In Rush Hour 2, a suspect is nice enough to strip for Jackie Chan and Chris Tucker in front of a huge window ...
... and That '70s Show also riffs on Rear Window by having a wheelchair-bound Fez watch Donna's mom, Midge, who conveniently pauses in front of a big open window before getting naked.
We enjoy gratuitous nudity as much as anyone, but we're begging screenwriters to remember that Rear Window used a brutal heat wave to explain why everyone was keeping their windows open. So write some excuse, even if it's a subplot about a prolific curtain thief sweeping through town. Anything!
