ROTJ may not be the best of the trilogy, though I never considered it the worst of the trilogy. I love all three movies, and could probably never pick a favorite or least favorite. I think that ROTJ has some phenomenal scenes in it, like the final scenes with the emporer and Darth Vader and Luke, and the death of Yoda. I also think that the Ewoks are an important part of the story. They show that you don't need firepower to bring down an army. All you need is the will to do it. This theme parallels itself within the storyline of Luke and Vader. Luke couldn't defeat Vader or the Emperor, but he had the will to turn Vader good again.
