TOD:
I thouroughly enjoyed the first two Star Wars films (A NEW HOPE and THE EMPIRE STRIKES BACK.) In fact, I liked each of them enough to go see twice at the movie theatre, a rarity for me. I wasn't a FANatic--in fact, the explosion of fanaticism around the films was a turn-off for me. But there was no denying that I was captivated by them and it was obvious to me that they were made with a great deal of love (the second movie being made with a great deal of more money, which didn't matter because it showed up on the screen.)
THE RETURN OF THE JEDI was a complete disappointment for me. This one seemed to have been made with a great deal of love *of* money. Overblown, under-directed and a slapped-together script. The much dreaded Emperor turned out to be a cackling variation of the Wicked Witch of the West. The obnoxious Ewoks clearly created for the toy market. The climax is a repeat of the first movie. The cast mostly just stands around between action scenes (Carrie Fisher admits that she was coked out of her mind during the entire shoot.) Only Mark Hamil manages to do anything with his Luke character. Just a completely sour and dissatisfying end to the trilogy...
I saw the first of the three prequels in a movie theatre and hated it from start to finish. As BK said, the acting from most of the human cast members was non-existant. And I cringed everytime the Jar-Jar thing appeared on the screen. I watched the second prequel on dvd and didn't think much of it, either. I've never seen the third.
