I really don't understand how anyone over the age of 12 can watch the ROTS duel between Obi and Anakin and not think its fairly ridiculous. From the balancing acts all the way to the "high ground" it is just nonsense and worse, not very exciting -- there is no moment of threat, danger or genuine suspense.
Granted, the duel between Ben and Vader in ANH was never that great. It was the idea. Lucas nailed a perfect saber duel in ESB. The duel in TPM was also quite well done (minus the superman leaps which were simply planted throughout to justify the necessary "jump" for Obi-Wan to flip over Maul).
