I just finished watching the 6 Star Wars movies over a two week period and since I don't own them, I can't go back and look at specific things.  Just rely on memory and what is out on the internet for information.

I don't know about you, but the 6th movie (3rd produced) leaves me with an unfinished feeling.  Here the rebellion just finished off the Emporer (or did they - we never saw him actually die), and there is one trained Jedi Knight and one untrained Jedi.  Back when the first three movies were out, I remember hearing that there were going to be a total of 9.  I was just reading an article on the internet that came out just after the 3rd movie (6th produced) that there were supposed to be 12 movies.
