The last few books I've read (or tried to read) have dragged on for months, so yesterday I picked something off the shelf on a whim and dived in. I finished The Graduate this morning, not just because it's dialogue-heavy and bare of description, but also because the characters act without a show of reasoning. When Ben Braddock and, later, Elaine Robinson are asked to explain themselves, they can't. I had to read and see what they did, then speculate why they did it.
This was a refreshing change from the bulk of books that delve into characters' thoughts. I appreciate that style, but it's good to remember I don't need characters' actions explained. Not employing the usual reflection, Webb allows readers to make what they will of what takes place—much the way a play doesn't lean heavily on stage direction, allowing a director and actors' interpretation.
The one drawback was, in lieu of detailed descriptions, my mind filled in Dustin Hoffman, William Daniels, Anne Bancroft, etc. in their movie roles. I wanted to see the characters as Webb saw them before the movie was made.
