How did the Jedi allow the Dark Side to cloud their vision or weaken their powers, after what I believe is years and years of a void in Sith? I'm not much up on the EU, but I would call it being arrogant to overlook the growing threat of Sith. If the light in your flashlight start to go dim, you darn sure better do everything you can to find out if it is the wiring, the bulb or the batteries and fix the problem. I am sure it wasn't just one day the Jedi were weak. They had to have known their was a problem, and in knowing that, if they had taken the time to look, I would have to believe even in the early stages they would have had the power to sense the Sith just down the street.

In the vein of arrogance, they believed Anakin was dangerous and that he could spell trouble. But as you can see in this film, he is probably the most powerful Jedi alive. He is heralded as a great warrior, pilot and swordsman. While his Jedi powers may not be as strong as Yoda's (which is to be seen), he is obviously in the upper level. So why allow for the possibilty of exclusion when it comes to Anakin? Why create an situation that could create an enemy out of a friend. As far as the war went, he was their equal, he lead excursions equaling that of any member of the council. He had every reason to be on that council as much as anyone, yet they treated him as if they were above him. Was he dangerous? Yes, but if they had not made him feel as such an outsider of what truly was going on, he would have not felt deceieved and his fate may have been different.

Thanks for bringing up Qui Gon, of which we don't get delivered...jerk!
