It is perfectly reasonable to have a damn talky first draft. You don’t know everything about your story or your characters yet, but you’re sketching in scenes in the order and direction of the plot.
So you take a shortcut and have your characters sit down and talk about what you know is important to establish. For your own understanding of the story. The way you ultimately tell that story is another matter entirely.
After you finish your first draft, there is no excuse for keeping your own nuts and bolts scenes. You have a thousand thematic and character developing choices to make in crafting that beat into something other than a chat and chew.
Look at your dialogue scene. Does it say anything that is obviously crutching the script along, such as “Hey, guys, Paul’s wedding in Hawaii next month, are you excited?”
