Faulkner's technical style shifts throughout that novel, ranging from simplistic and completely extroverted (Benjy) to lyrical and drawn out (Quentin).
Authors like these deserve the benefit of the doubt. Before you simply dismiss an author because he appears, on first notice, to be difficult, ask yourself "why would an author employ very long sentences?" You wouldn't pick up a Shakespearean play and say "Oh, Shakespeare uses 'thou' and 'ye', I give up!"
