Don't even go there, the climax of that scene is one of the most stupid things in the Star Wars saga (and lets face it there's some stiff competition in there). A Sith Dark Lord with some of the fastest reactions in the galaxy (and who's just handily fought off two Jedi before dispatching one comfortably) waits with gob agape for Obi-Wan to leap upwards from a position hanging off a light fitting and pull a lightsaber towards him before letting himself be cut in half...
Yeah i do agree the end to the duel is a travesty, Kenobi farting himself out of that hole and Maul just watching will go down in history but damn it was awesome getting there.... I still say Lucas should never have directed the movies, he's too caught up in tech and merchandise rights.
