Let's start out on a positive note, with what went right in this part of the film.
So those are my thoughts on Return Of The Jedi. It's an okay film: it has plenty of action and does a pretty good job of drawing the Star Wars trilogy to a close. But the plot line which takes place on Endor drags the movie down, killing the drama and making the main characters appear incompetent to the point of abject stupidity. Also, the Ewoks taking down the Imperial troops with sticks and stones is ridiculous. Science fiction doesn't have to be completely realistic, but it should make some sort of logical sense.
