Its a clumsy device for less than intelligent audiences......and SW has never made a habit of hiding huge obvious things just out of frame....so when one movie has a shot like that in it when the other 5 do not, I call that bad film-making. If the point was to give each film its own style in the way the characters or audience perceive things not on camera then it wouldn't be a problem....but the 6 films are stylistically similar for the most part...treating things offscreen as if they continued to exist (ie: characters can hear things coming before they arrive, sensors detect approaching ships)
