This is a pet peeve about the show; some parent/partner yelling at the staff to help the patient, accusing the Doctor of incompetence when answers aren't available yet, and just being royal pains in the fanny. Also, how many hospitals allow relatives etc, INTO the E. R. to hover all over the place, sometimes screaming at each other around the bed?
No hair coverings, no masks .... cheesy & unrealistic dialogue make for a train wreck of a series. Yet oddly (hence the generous rating of 5), it's easy to binge-watch.
When the mystery diagnosis eludes these paragons of the Hippocratic Oath, it's guaranteed a hot-headed control freak shows up to holler
.... "Do something, Doctor!!"
