All that David Copperfield crap

What JD Salinger was trying to say in The opening lines of Catcher in the Rye was, he was going to spare you of the immensely deep and precise details to build up characters and settings found in David Copperfield and other novels by Charles Dickens.   Dickens paints a picture in your head that compared to what Salinger did, it would be like looking at Mona Lisa and comparing it to the Weeping Women.
