ESB outclasses STAR WARS in terms of plot, pacing, action, acting , special effects and just about every other term I can conjure up in my mind.
there are a lot more issues with matte boxes and blue screen lines.
That’s only because there are more special effects. If STAR WARS had the same amount the number of especial effects as ESB these same problems would be more abundant in STAR WARS. But that’s because both films are products of their time and both aged relatively well IMO.
