You know, my favorite duel in the series is the one between Obi-Wan and Vader (and no not the one in Revenge of the Sith). The duel with the "worst" fight choreography is better than any of the duels in the prequels in my opinion because they actually look like they're trying to cut each other. Not to mention the fight is more emotionally involving because by that point in the movie the audience really cares about Obi-Wan, and doesn't want to see him killed. I hope Ep. VII doesn't make the lightsaber fights so pointlessly fancy; I don't have a problem with rehearsed choreography, but in the prequels it really seemed like whoever wrote those scenes thought the goal of a sword fight was to clash sabers with your opponent rather than try to hurt them. The lightsaber choreography should be more like the ones in Jedi and Empire: realistic and believable.
