We’re talking about TV shows and movies.

There’s normally one unrealistic conceit, eg aliens existing, that the audience believes. But then, the regular conceits like “The scientists studying the aliens speak like a bunch of robots and act like total idiots” become harder to believe.

I’ve heard this said, can you verify for me where the lawyer stands?

If his position is truly still behind his table, what if the witness/jurors are hard of hearing?

There’s a trillion ones around unrealism, so I may as well pick something that would be more enjoyable if fixed.

Professional chatter. Let’s say a team of 30 scientists have been trying to communicate with a dimensional portal for 5 years. They wouldn’t be using speech like “Identity verified. Doctor Faris, you are clear to approach the anomaly.” Often, they’d have extremely abbreviated lingo for everything they need to express that happens on a daily basis, and otherwise are chatting about other stuff.

“Ok, approach endorsed. Bob wasn’t so chatty yesterday from what I heard, we’ll just aim for 2 logic points for this cycle.”
“Ryan was suggesting we spread the cycles. Bob has to sleep sometime.”
“Yeah, 90% of us would rather listen to Ryan than Mick, but Mick signs the checks.”

So the only actual order comes from some obscure phrase like “Approach endorsed”, which they may only say verbatim for safety reasons. The rest is just workplace banter about how best to accomplish their task, none of it being essential. EDIT: And, to make clear, in the above quote, Bob is the portal/anomaly.

One plot point I liked of Nausicaa of the Valley of the Wind. The Tolmekians are growing a Warrior. Enemies are on the way. Their princess orders them to unleash the Warrior. Her second says it’s not ready. She ignores him, it’s sent out. It’s not ready, and melts almost immediately.
