Welles did such a definitive Rochester for me, exactly as my mind's eye saw him in the novel, that it is hard for me to appreciate anyone else in that role.  However, George C. Scott did a very good, very restrained Rochester in his later version and this version presents a very good Rochester as well.  Morton as Jane Eyre confirms my earlier opinion from her performance in "Sweet And Low Down" that she is an actress to watch.  As far as faithfulness to the novel, I really don't demand that from films which are a very different creative medium from novels. The basic story has become a timeless classic, often copied but never equaled.  Jane is a poor orphan who becomes a governess for Rochester's ward.  He is a wealthy man with a beautiful estate.  They fall in love but a horrible dilemma from his past comes forth to haunt them both.
