Abominus is right... A star would have no use, but to be able to do something like that requires an amazing command of the force, and thats why its often said in threads like this. Of course it wouldn't make him win because he would die too, but he does have the ability something that others do not have. Quite amazing if you ask me.
And there a few reasons why Jedi are weaker in the movies
- Less actual combat training, they didn't have mayor wars for a thousand years and were not ready to fight one. They had no idea how to battle with other Jedi and Sith and would have suffered greatly at the hands of this people that did fight their entire life.
- After a thousand years of peace training methods get aimed more at peace keeping and deflecting blasters and shit like that instead of fighting like during the golden age of the Sith.
- The Sith are a lot weaker because of Bane his rule, with more Sith there were more to test yourself against and the strongest would always rule. Bane his rule could help secure the safety of a Sith Empire, but it Could also very well be its undoing because you only have toe worry about one opponent instead of a thousand and you become weaker because of that.
The biggest difference is basically the peace thing, less fighting means less training for war, less experience in war and all that crap. Thats why Ancients win a lot of the time from most PT and OT people, they grew up in wars. Always fought wars, always trained to kill or defeat other Jedi and Sith.
