I saw someone make a good point in a review that I'm surprised I hadn't thought about before. Now, I enjoy Return of the Jedi a lot - my third favorite, thought it isn't without it's problems. However, reviewer made a point that the second they enter Jabba's palace, Lucas changed the tone of Star Wars. Before that, with 4 and 5 it was much more serious in tone (with some humor of course). Then when he did the special edition changes, he continued that. This is more of a throwback to the first two films.
