There are certain phrases that permeate the zeitgeist like low-hanging fruit. The moment you read one, your eyes glaze over.
“I don’t think we’re in Kansas anymore.”
“We have to talk.”
“Move it, people!”
“I know, right?”
“I can’t even…”
Comic book writers feel pressue urge to add words. There’s all that space! For what are we being paid if not to add words? The habit is especially egregious during fight scenes. A real fight is physically demanding. Even the best fighters, who train for months, run out of gas and simply don’t have the energy to talk to their opponents. There are always exceptions, like Muhammad Ali and Nate Diaz. But most of the time, you’re out there panting trying to outguess your opponent.
Forgive me Father, for I have sinned. I too have added unnecessary dialogue to fight scenes. And I just used a cliché! You see? It’s everywhere!
Show don’t tell is among the most important lessons a writer must learn. This applies to prose as well as comics. Comics are a visual medium, and anytime you can advance the narrative by showing, you should. This doesn’t mean a wordless comic. Dialogue can advance plot too, but it must arise naturally from the narrative. Use dialogue to reveal character or add a touch of humor. Shakespeare understood the importance of humor, which provides brief flashes even in his darkest tragedies. Even Schindler’s List has a few jokes.
