Those who can stand to watch Millennial era movies more than I can have noticed that there are way too many close-up shots nowadays. See David Bordwell on the topic here and here, as well as a lengthy thread on the forums at cinematography.com.
Close-up shots allow us to read detail on the face, but obscure body language and posture, as well as the setting. We generally only see one person at a time, so we don't get to see the interaction between characters — only cutting from one to another. Other people are part of the setting, so we also can't see how the characters are placed with respect to one another in space, nor where they're facing (e.g., are two characters looking at each other during an exchange, or is one of them facing / looking away?).
A common complaint is that this overuse of close-ups makes a movie "look like TV," where the norm is one close-up shot alternating with another for each line of dialog, on and on and on.
I don't care for contempo TV shows either, so this sounds a little off. My hunch is that TV didn't used to rely so heavily on close-up framing and shot / reverse shot editing. That would mean the trend has affected both TV and movies, though perhaps being even more common on the small screen.
Let's investigate, shall we? I'll take it for granted that today's lame-o shows follow the close-up approach, if everyone says so. But I also checked the trailers on YouTube for the first and second seasons of Orphan Black, one of those trendoid "edgy" shows that styles itself as breaking new ground but is jumping on the bandwagon of the look du jour. It too is mostly close-ups, and minimal movement from either the camera or the actors.
What about older TV shows? Sit-coms are out because comedy, even today, is shot from farther back so we can see the characters interacting with each other, and see their reactions to each other in real time rather than interrupting one's expression to catch a glimpse of another's. That leaves action and drama, which have both undergone the shift toward close-ups. Fight scenes today are shot close up and tight around the characters. And drama unfolds in alternating close-ups of two people standing still or sitting down.
Well, I've already written an off-the-cuff post about how engaging the camera work was on Magnum, P.I., so why not continue with that example? It was one of the highest-rated shows in the '80s, its theme song landed on the Billboard charts, and it's one that anyone would nominate for definitive '80s TV shows. So this isn't cherry-picking.
It's also worth studying because it was an even mix of action and adventure with drama and mystery — and not comedy. Does the dramatic dialog unfold in shot / reverse shot while close up? Does the action lock right onto subjects, blocking out the arena that it's taking place in?
I'm certainly not going to review every episode, or even do a close reading of one scene in one episode. That could be cherry-picking. Instead I've put together an array of 20 screenshots that come from the thumbnails of full-length episodes available on YouTube. This places each shot halfway through the episode, not at a spot that I purposely chose to make old TV look better than new movies. I didn't cherry-pick which episodes I included either — the first ones that came up in the search results.
Here is a just-dropping-in look at a couple dozen episodes of Magnum, P.I. (click to enlarge):
None is shot up so close that only the face is in view. The single shots are from far enough back that we typically get a sense of place from the setting. The somewhat closer-up shots are two-shots where we see characters interacting with each other, using their hands and upper body language. Plus that two-shot of the not-so-friendly dogs. Just think of how much we'd lose if we only had a close-up framing the dogs' heads -- are they even facing toward some character, or are they just the type that barks indiscriminately? Quite a few have more than two characters interacting, and placed at different distances from the camera.
Read that earlier post on the show for a closer reading of how particular sequences tend to play out. The blocking is not just "enter room, walk straight to standing / sitting spot, and start blathering for five minutes." Actors move around the setting, often at different distances (e.g., someone pacing nervously in the foreground, while another leisurely strolls around in the background, with a wall separating them so neither is aware of the other, but with a window through it so that we can see both movements).
Lots of examples too of what Bordwell calls "the cross," where A begins on the left and B on the right, and their paths lead A to the right and B to the left. Simple switching like that makes us attend more to the action, rather than tune out spatially once we know that A has plopped down here, B has plopped down there, and they'll never move around until they need to leave the scene.
While on YouTube, I watched some scenes from an episode of Columbo, and there too there was no heavy use of close-ups. Indeed, the most famous staging of characters on that show has Columbo in a medium or long shot, almost ready to leave the setting when he remembers "just one more thing" that leads him to backtrack into a closer-up shot to ask the suspect another couple of questions. Like Magnum, P.I., that show combined mystery and drama, though not action (or comedy).
That's my take on what's going on in both TV and movies from the past 20-odd years — a shift away from mystery, anticipation, and tension, and toward obviousness and instantaneous reflexive responses.
Before, you could clearly perceive the configuration of the characters relative to one another, relative to the larger setting, and their trajectories (relative to each other and within the setting). You can't anticipate with projecting a current movement forward. No path of motion, no anticipation. But anticipated outcomes are not actual outcomes — you're held in suspsense until the climax or pay-off where you see if what you were projecting actually took place or not.
With super close-up shots, all that stuff that would've been included in the frame of reference has been sealed out, and you can't project where anything is heading. If there's no action, the result is dull. If there is action, the result is disorienting rather than engaging. Either way, close-up after close-up alienates the audience.
This ties into a separate but related shift in editing away from longer shots and toward a rapid pow-pow-pow rhythm. A single fluid shot allows you to anticipate the outcome, be held in suspense for a little bit, and then see if it happened or not. The interrupting back-and-forth rhythm prevents a physiological reaction from building in intensity, or develop into a full emotion or thought. It's like your sex partner switching positions every 1.5 seconds — dammit, just hold still for a little while so we can get it on.
But the ziggy-zaggy rhythm is a topic for another post. (See how annoying these abrupt cuts are?)
