Re: The really annoying thing is>>
The biggest problem with most of the stuff tagged onto the Star Wars universe is... light sabers and Jedi. Everyone loved Dark Forces, but lamented that there were no light sabers in it. And everyone wanted to say "use the force, Luke" and there was no force either; so they wrote Jedi Knight. But rather than flip to a "golden age" à la Old Republic, they set it just after the films, which meant suddenly injecting all those crazy force powers that then end up being reflected back in the prequel trilogy.
The books and comics not only immediately started introducing Jedis so they could have more light-sabers, but they also all played up this pre-Empire superpowerful Justice-League-of-the-University Jedi Council nonsense, and suddenly the Jedi went from being a few relics of an ancient way of life, mocked and derided by many (see Vader's argument in New Hope and Jabba's dismissive "he's using an old Jedi mind trick" in Return of the Jedi) to being a bunch of walking one-man armies armed with more pyrotechnics than the all the Earth's national holidays put together who were wiped out within the living memory of half the characters in the films.
Kenobi and Vader only made sense as the end of a long slow decline in the traditional ways.
The orequels would have made more sense if Kenobi was just a soldier and was laughed at for carrying a light-saber into battle, and if there were a handful of others like him using the force subtley like in the original films, and Annakin Skywalker was one of them, perhaps even a young soldier that he had trained hiimself.
