What is the author's style in Journey to the End of the Night by Louis-Ferdinand Celine?

By speaking in first person, as though telling the story from memory, the main character directly and vividly conveys his thoughts to the reader. Bardamu's narrative voice is full of black humor, cynicism, colorful exaggerations and fantastic embellishments. Bardamu's witty yet perceptive tone helps us to enjoy his otherwise pessimistic and misanthropic outlook.

Bardamu exaggerates for the sake of telling a good story and therefore is not factually reliable. Instead, he seems to be aiming at some deeper truth by his selective emphasis and hyperbole. This is easily seen in the chapter where all the hospitalized soldiers compete to make up heroic lies, the best of which are performed in the theatre, La Comedie Francaise.
