Ok. So its something im sorta frustrated with in movie and film plots. Its where the characters seem to intentionally not tell other characters things for apparently no reason. So its like a fair amount of the plot would not exist if the characters would just mention relevant things.

It’s always been a common sign of sloppy writing. At the very least, a writer should create a situation that believably prevents the passage of information. Not just people being too stupid and emotionally blocked to tell each other. That goes for “I love you, and I’m sorry” and also for “the murderer is…”
