here is the problem. you are looking at this all from the perspective of looking back on the OT duels AFTER watching the PT films. You must look at the OT duels before the PT came out. No one thought the duels were WEAK or SLOW or not flashy. Sure we all thought the episode 5 and 6 duel was better than episode 4 but that had more to do with budget and time. the new hope duel looks no more slow than the sword fights in sparatca and other time period pieces.
after you view the PT duels your view becomes bias and you have to make up reasons and excuses for why the duels LOOK DIFFERENT. they don't look different because of character flaws or traits they look different because LUCAS brought in a completely different style of sword fighting and trainer to teach the actors to use. that would be like me bringing in a guitar teacher like albert lee or james burton or brian setzer to tech the OT cast to play country or rockabilly and then bringing in eddie van halen or slash or joe satriani to teach the PT cast rock or metal. sure both cast are playing guitar but they are playing two different styles so they sound completly different. n the movies case they LOOK completly different because of this.
this tarnishes peoples views of the OT films especially young fans who grew up with the PT films and have to look back on the OT and say such garbage like vader was weak he was a machine and was hendered. vader was NOT weak and has never been weak. vader was the baddest guy in the galaxy and he fought that way cause the screenplay was written for him to and the character was taught to that way.
