Every director's cut I've ever seen has been a massive piece of shit because the director thinks that every inch of film he shot is solid gold and crucial to the story and it's the editor's job to tell him that stopping the movie dead so that they can add a poorly-acted redundant scene will ruin the pacing of the film. Also, most director's cuts are released 20 or 30 years after the theatrical version, and Coppola and Ridley Scott and shit were way worse at making movies in 2004 than they were in 1980.
