It did feel choreographed, but I still thought it was great fun to watch, and one of TPM's redeeming factors. After that duel, I truly expected great things involving lightsabers to come from the next too films, and six years later I was sorely disappointed (yeah, Obi and Anakin's fight was pretty lame, we knew exactly what was going to happen, and its score felt to much like a rehash of Duel of the Fates, the acting was wooden, and it had to be experienced in the wake of the realization that even though you had crazy low expectations for this film after seeing AOTC, the movie still managed to suck a lot harder that you though it would). TPM's duel was the consolation of the film not having met expectation, even though it disappointed, that duel made you want to leave the theater's exit only to go back around to the box office and buy a ticket to the next showing. It was awesome, only one of the three fighters fate was written in stone, and all three fighters were by far the best characters the PT would ever have to offer. That said, I cetainly don't things TPM stylized three way duel does anything to harm any of the OT fights. Empire Strikes Back's duel is still very powerful, and much more meaningful. The hero goes to face his fate in the classic confrontation of an evil nemesis, and he freaken get's his rear end handed to him on a plate! Who saw that one coming in a world full of happy endings? In the last film things looked bleak, but the hero saved the day just in the nick of time. In part two he gets his hand sliced off, and is told that the man who he thought killed his father is his father, then he attempts suicide.
ROTJ's battle is also a very powerful battle, and one of the few things that without dispute was done perfectly in ROTJ. It is perhaps one of the finest final show downs ever committed to film.
TPM battle is just good fun, a little touching when the apprentice watches his master die, and realizes he is on his own now. But none of that compares to what we see in ESB or ROTJ. And the Yoda saberfight in AOTC was amazingly lame, reminded me of Kermit the frog dueling in Muppet's Treasure Island, not sure why. I felt embarressed to be watching the movie when Yoda started jumping around like a loon. And I nearly started laughing when Obi-Wan and Anakin where hovering over the lava riding on the backs of droids. Oh, but Palpatine's big fight with the three stooges, two of them going down in the first two seconds, gets the award for the worst saber duel of all time, and the acting in that scene managed to make it even more unbearable that it already was.
