I've always referred to Star Wars as "The First Star Wars", and for the rest "Empire Strikes Back" and "Return of the Jedi"
Also, add me to the camp where the opinion is Star Wars and ESB were great, RotJ was 'so-so'. I remember trying really hard to like the ewoks because how I loved the first 2 movies so much. Sometimes I still try to trick myself into liking them even today.
