I didn't find this novella to ba as impressive as other works of Murakami. It uses much of the devices found in his previous books with the exception of focusing heavily in some chapters on playing with camera angles. What I'm referring to is those omniscient, first person plural (we), chapters where the camera literally zooms in and out of the scene to elaborate on the general and specific details - this technique did little to enhance the storytelling and, if anything, felt detracting from the more interesting aspect of the narrative.
Still, as an admirer of his books, I don't regret reading 'After Dark'. A writer, after all, has to experiment and avoid monotony in his work.
