I don't think there's that much realism in normal TV and movies. The way people are made up, the perfection of their hair and wardrobe, the lighting, the exaggerated sound effects, it's all heightened or artificial in some way. Not to mention commonplace, intentional unrealities like thunder sounding simultaneous with lightning, rain always pouring down very densely after a single initial thunderclap, bullets sparking when they hit metal, blood or debris blowing out backward from a bullet hit, etc. You can lull yourself into accepting these things, but compare them to reality and they fall short.
Not to mention the characters who deliver dialogue far more smoothly and free of clumsiness than most of us talk, and the events that progress more coherently or dramatically than our own lives do. Or the characters who look and sound exactly like actors you recognize, or like characters you know from other shows. (Gee, David Banner's a dead ringer for Eddie's Father!) Or the fact that there's music playing over the scene but nobody in the scene seems to hear it. It's all unreal. If something seems acceptably close to reality to you, that's because you've chosen to set your threshold of disbelief above its level. It's just a question of where you decide to place that threshold.
