Today, I declare war ... on decompression.
Comic books aren't storyboards for films. The filmic viewpoint has infected the art of comic book making. I have nothing against movies. I like movies. Some of my best friends are movies. But comic books, sir, are no movies. I'm not saying that filmic devices and techniques can't be used in comic books. They can; but you can also brush your teeth with a mop.
Control over time is essential to the art of film-making. Unlike a book, where the reader has the choice of how quickly they experience the events of the story, a film decides not only what you will see but the rate at which you will see it. Comic books don't have that luxury. Oh, sure, they can fill a page with static panels to denote, say, an awkward pause in a conversation. But we don't feel that the way we feel in on screen; the mind just skips over the inactive panels and goes to the next word balloon.
Here's the world of "compression", exemplified by one of the great works of literature "The Monster That Loved Aqua-Jimmy" (as I recall, a copy was included in the Voyager payload).

PANEL 2: "You're now Aquaman for a day!"

PANEL 3: "Hey, I'm Aquaman for a day now!"

PANEL 4 "A challenge to my new powers ... from a pretty girl!"

Okay, perhaps "The Monster Who Loved Aqua-Jimmy" isn't great literature. But it does not dawdle. Advancing the plot is paramount; comic books are about plot. Character moments are extremely enjoyable but they should be the beautiful scenery viewed from a hot-rod plot; please do not slow down, pullover, or (Schwartz forbid!) take a detour to find a character moment. If you can't find opportunities to reveal character in the natural course of a moving a plot along rapidly, then you should be writing novels, not comic books.
Let's compare "The Monster Who Love Aqua-Jimmy" to a more modern story ....

Justice League of America #2

Justice League of America #3

Justice League of America #4

Now, I am aware that there are other things going on in those issues. I'm familiar with the Levitz model of advancing multiple plots and subplots. But I think you get my point; it seems that more happens in the first four panels of "The Monster Who Loved Aqua-Jimmy" than in the first four issues of the Justice League of America. This is what comes of editors encouraging creators to write novels using comic book characters rather than writing comic book stories.
I don't mean to pick on JLA or its writer, really; many modern comics are like this, since we live in a world where "stories" have been replaced by "storylines". I just wanted to pick one that most of my readers would be familiar with.
And please don't hand me that hokum about the economic necessity of writing for the trade. It shouldn't be an excuse to puff out what should be an action-packed 20 page story into a six-month snail race. If trades were composed of six action-packed stories (perhaps with some underlying theme to justify their compilation) rather than one bloated faux-epic, they would sell better, not worse.

Decompression is unsatisfying. Decompression is a root beer that's 80 percent froth. Decompression is like 4 hours of warm cuddling when you want 15 hot minutes of woo-hoo. If I wanted decompression I'd be reading Victorian horror novels like Frankenstein, with its chapter long digressions on Alpine scenery, not a sprocking comic book.
You know how many panels there are in Justice League of America #1 without any captions or word or thought balloons? Twelve. You know how many such "silent"panels there are in "The Monster Who Loved Aqua-Jimmy"? Zero.
In film, the director controls the passage of time; in comic books, the passage of time is in the hands of reader, who can take the story as slowly or as quickly as he likes. That's why filmic tricks like "silent panels", by the way, backfire. They don't create a sense of pacing and slow down your reading; they speed it up.
Think of those two or three page sequences where the characters silently engage in kick-ass martial arts conflict. Exciting, aren't they? Of course not; no matter how well they are drawn, you naturally blank over them ("Oh; fighting.") and dash forward in your reading to the next written word. In film, such scenes are exciting; but comics, like it or not, are a static medium, and such scenes read like Egyptian wall paintings. Why do you think comic books so often have people talking, thinking, or being narrated during fight scenes? Why do you think fight scenes are spiced with energy blasts, batarang throws, giant props, and needless acrobatics? They are speed bumps.
Slow storytelling means fast reading; fast storytelling means slow reading. The first is boring; the second is exciting.
You can dash through modern decompressed stories in moments because the rate at which you read is determined by how much is happening in the story. Try to dash through a story like "The Monster Who Loved Aqua-Jimmy" that way and you'll get a pounding headache after two pages. Compressed storytelling is exciting literary espresso; decompressed storytelling is boring weak tea you have to drink gallons of to get even a slight buzz.
Compressed storytelling has gotten a bad rep because it's associated with crappy stories. Yes, many of the stories written before the advent of decompression were stupid, but that doesn't mean they were stupid because they weren't decompressed. Sure, un-decompressed stories are challenged to get in the necessary exposition without using bursting word/thought balloons. But, face it, we have to suffer through those in your average Wonder Woman story anyway; wouldn't you rather have them advancing the plot than simply being so much empty badinage?
Think that a modern balance between quality and compressed storytelling isn't possible? Hogwash. There are many examples, but the easiest thing to do is read some Justice League Unlimited. Small wonder that JLU is popular with longtime readers yet still accessible to new readers and children.

a panel that contains both necessary, plot-advancing information and
a gratuitous but delicious character moment.
Apparently such things aren't impossible, after all!
Decompression, by the way, makes comic book myth very opaque to new readers; too little information is conveyed about who's who and what's what. Decompression is only possible if you rely on the reader to know a lot of information you aren't willing to stop to explain (What is that purple starfish? Who are Felix Faust, Prof. Ivo, and T.O. Morrow? Who the heck is Trident? Geez, I don't even know who Trident is). Decompression is the enemy of comic books because it's the enemy of new readers.
DC; stop worrying that your writers are going to run out of ideas. Stop worrying that longtime readers will be annoyed if you repeat an explanation of a character or their powers. Stop worrying that your readers are going to get the bends without decompression. Return to the done-in-one, the back-up story, the high-octane elements that employ the medium's strengths rather than its weaknesses, and the kind of storytelling that only comic books can do.
