Neal Adams was the most influential artist at DC Comics in the late 1960s, creating the template for subsequent depictions of Batman, among other jobs. He later designed the second Robin costume.
Here are some of Adams’s thoughts on storytelling from a sidebar in The Insider’s Guide to Creating Comics and Graphic Novels, by Andy Schmidt, editor at IDW and proprietor of Comics Experience.
With comic books there's a contract with readers. And it works like this:The last part being an essential aspect of serial storytelling: you gotta bring ’em back for the next installment.
I'm going to tell you a story. If you will be good enough to read my story, I will not trick you, I will not slow you down, I will not give you something that you don't understand. Unless, we agree at this time, it's time not to understand something but I'll explain it to you later on. But I won't keep you in the dark for so long that you get bored.
So if you take my hand and read my story, at the end it will have a good ending and you will be happy, and you will come back next time and read another story.
