This show is pretty good so far. I went in with very low expectations so the medicine actually being pretty spot on is impressive. Obviously the acuity shown between 7a and 9a is outside the realm of reality but they're also showing us an ED with a physician in triage and so boarded up that only higher acuity patients are making it back.
I'll be curious to find out how they managed to keep the medicine and the character's challenges (boarding, patient satisfaction, burnout, etc.) so close to reality.
For Scrubs, a show famous for the accuracy of its depiction of medicine, the authenticity was because Bill Lawrence (the creator of the show) used his best friend from college, a Cardiologist, as the show's medical advisor. I believe that as opposed to hiring an advisor that he could get to ignore as soon as is inconvenient to the narrative of the show, using someone he had a real personal friendship with is what contributed to the accuracy.
There's a real life ER doc or group of ER docs that are behind a lot of the writing of this show and I'd love to find out how they pulled it off so well, at least for two episodes.
