first no grievous was nto even force sensitive enough to become a jedi, let alone be more powerful the yoda and anakin. he was more like a thrawn character. who was super brillent. it was actually sidous who found him, put him in the hands of one of the seperatists, who then arranged for a crash that almost killed him, and destroyed his body. they did all this so that the coudl get into his mind and turn him into a crasy cold hearted general. the reason he was able to kill jedi is cause his body was designed to make movements like jedi, and dooku who according to the PT novels was one of the best sword masters in the history of the jedi. if you can imagine how much a car junky knows about cars well, dooku was the same with with saber fighting. anyway thats why grievous was able to kill jedi, cause he was designed with super strength agility, and trained to use his body, rather then programed.

as for the trageaty of Darth Vader, man they really flesh out what turned anakin, and i dont know how they could have put that in the movie without a narrorator.

hey do you think it would have been cool if the whole PT had been told as a tale from the ghosts to luke after the OT. to have everything narrorated by yoda, obiwan and anakin, and have eash complement eachother as they told the story. i wonder if that could still be done really easily, or if that could be made in a fan edit. it would take ALOT of work involving finding a voice actor and a makeing a good script
