All art is driven by form, to a certain extent. Deciding to tell a story by writing a novel means a different form, with different strengths and weaknesses, than telling the same story by making a movie (which is why it’s often fruitless to compare adaptations to the source material). But sometimes creators will intentionally confine themselves even more, prioritizing form over traditional storytelling techniques. There’s recently been a couple of really interesting examples of this on TV.

The first to debut (although we came to it late), is The Pitt, the Max medical drama that is absolutely not a reboot of/sequel to ER.

Set in a takes-all-comers trauma center ER in Pittsburgh, the show’s catchy gimmick is that the 15-episode first season follows a single shift in the ER in real time (if you’re thinking such a shift couldn’t really be 15 hours long – it’s not an average day!). Noah Wyle (yes, of ER fame) plays the head doc as he rides herd over a bunch of residents, med students, and other medical professionals through the day.

The second to premier, which it did with a blast, was Adolescence, a British Netflix limited series about the investigation of a teenager’s murder of a teenaged girl.

As with The Pitt, Adolescence has a structural gimmick, too – each of the four episodes is done in one shot, so that it not only plays out in real time (for the hour – the series actually covers months of time in the end) but pretty much in one location. The first episode starts when police raid the suspect’s home, then follows him and others to the police station and the eventual reveal that he did, in fact, kill the girl. Other episodes feel a little more contained, particularly the third, which is basically a pas de deux with the killer and the psychologist trying to understand him.

In both cases, the format of the shows put limitations on how those stories were told. With The Pitt that began early, as they had to build the labyrinthine ER set before they could actually write anything. Given the “real time” framing, they had to know how long it took for people to get from place to place and what would be visible in the background of shots to know how all the pieces fit together. Likewise, in Adolescence the one-shot conceit meant there were no quick cutaways to other locations and other characters. That led to a tight focus on the killer and his family, to the exclusion of the victim or her family. As a public defender I found that focus refreshing, as often not enough attention is paid to the toll that crime takes on the perpetrator’s family. Nonetheless, it did lead to some criticism of the show for that focus.

What does that mean for how the form of these shows impact the viewing experience? I think the one-shot conceit for Adolescence makes a bigger, and more powerful, impact. The first episode expertly hands off from character to character, setting the scene at the station leading up to the killer’s interrogation and eventually admission. There are times when he disappears as the camera follows other characters around, reinforcing his isolation. The final episode, which includes a drive to the UK version of Home Depot after kids vandalize the killer’s father’s van, uses the drive time to supreme effect, giving us genuine human moments that, in other formats, might not land as well. The third episode, which is just the killer and the psychologist, is the least flashy but is intense. Only the second episode, where cops go to the school where the killer and victim went, feels a little hard done by the format, mostly because it’s a pretty big campus and there’s a lot of walking to be done.

The conceit feels less present in The Pitt. The most notable thing about it is that it avoids the typical medical drama pattern of wrapping up particular patients at the end of the hour. Some patients linger (and linger) for several “hours,” giving a better sense of how long ER visits tend to be. That said, aside from the slowly ratcheting up of tension over the hours there wasn’t one point where I was like “and that’s why they did it this way!” And the “one shift” idea drags down the reality of it a bit as no such horrible ER shift has ever existed in the history of the world. I would have liked to have seen a down hour where nothing major happens, people get a chance to breathe, and such. In the end the format works, and it doesn’t get in the way, but I’m not sure how essentially it is to the end result.

Art isn’t created in a vacuum. It’s shaped by the times in which it’s made and by the people who make it (who, themselves, are products of the times in which they’re made). Sometimes, artists will add additional barriers that shape their work and it can produce something really cool.
