Just Meursault

Throughout, The Stranger By Camus, Very little happened that showed much emotion in regards to Meursault.  He had a trial where it was just bleh.  I could compound a much better world then bleh but it was.  Books and movies usually like to make the audience engaged with the seen and what's happening.  But I feel like Camus is trying to tell us something through nothing.  So what does all this tell us?  Why does Camus present us a story about someone with no emotion and with little introspective in his life?
