OOOOOkay, hold onto your asses, assholders cuz this is gonna be a long one.
Not all Jedi are equal, the force is stronger with some then it is with others. Prime examples, Anakin Skywalker, Master Yoda, Mace Windu. The reason they're on the council giving out the Homework assignments (bar Anakin) is becuase they are the most skilled and adept in the ways of the force.
However, any Jedi can fall to the dark side if the temptation is great enough (Apart from Yoda, I'll eat my lightsaber blade before I see a Dark Yoda).
Also some people are banding around the tennents of the Old Jedi Order;
A Jedi shall know not fear, nor pain, nor love (or whatever, you get the gist).
A Jedi order wiped out by order 66. By the end of 'Jedi, luke is the only one, and what's he do? Goes off and founds the NEW Jedi order. Then what does he do? Goes and gets himself a wife! Mara-Jade Skywalker! and a KID! Ben Skywalker!
So, if you want to be a Jedi, you may not have as many cool superpowers as <insert tired generic DC/Marvel Superhero here> but you'll probably have some degree of pre-cognition, speed and agility, not to mention a freaking LIGHTSABER, influence over the weak minded, the opportunity to fall to the dark side, a cool Astromech droid to follow you around and make beep-boop noises.
Now...a Jedi in the Warmachine Armor....Kiss my ass, Emperor Palpatine, I'm coming to get you!
