I've heard a lot of people ripping on lightsaber fights from the star wars movies, such as the fight between Obi Wan and Anakin. They say that the Jedi fight in an unnecessarily elaborate and unrealistic way, and that they fight for much longer than the duration of even the longest real sword fight. I would like to take some time to offer my own theory as to why this may be. "He can see things before they happen, that's why he appears to have such quick reflexes." -Master Qui-Gon As we know, the Jedi are a race of "Force sensitive" beings who, even when not explicitly trained to channel the Force, can see moments into the future to predict what is going to happen. If Anakin shows this ability at a young age, how much more would a Jedi knight be able to forsee coming threats? It follows that, for the thousands of years that the Old Jedi order had existed, they would have developed a Jedi vs Jedi fighting style that would counter this precognitive ability. As that style progressed to the point at which we see it in Episode 3, it would have strayed so far away from what modern masters think of as sensible swordplay that it would almost seem rediculous. Perhaps when spinning one's saber around like a fool, you keep open any angle of attack so that you can decide where to attack at a moments notice, limiting your opponent's ability to predict your next move.
