The Jedi Rocks scene was originally attempted. In the Special Edition documentary we see stock footage of such a scene being attempted. I don't like this change either but lets face it Return of the Jedi is by far the worst Star Wars flick. Stuff that was always there is far worse. I am also so happy he got rid of that horrendous ewok song. The Sarlacc pit is one of my favorite changes. It works well with the original footage and really makes that thing so much more alive.
