>>>I think what Dr. E is saying is that we didn't know of the prophecy or any chosen one until the PT came out. And that does drastically change the framework of the OT. It diminishes Luke's role in the entire series. How so? Luke's mission doesn't change- he's still trying to bring back Anakin, and he's still doing it for exactly the same reasons. What the prophecy does isn't changing the framework of the OT, but putting the OT inside another framework, and turns it from a trilogy into half a saga- but nothing within the trilogy is changed. If anything, in having him working for the Force to help Anakin fulfil a prophecy he knows nothing about, what it does to Luke's role is puts it into a bigger picture. He's not just the last hope for the Jedi to not die out- he's the last hope for the universal balance to not be destroyed forever. Nothing about what he does or why he does it is changed. >>>The prophecy itself was never mentioned, nothing was said to the audience or to the other characters in the movies to indicate the existence of a prophecy about 'one who would bring balance to the force,' or how this person might be a threat to the emperor. No, but we're not talking about a Friday XIII part 9 type, "The emperor can only be killed by a special lightsaber wielded by a member of his family" addition here. We're talking about something that not only seamlessly fits in with the original trilogy, but also fills in plot holes that had to be resolved- such as why Obi Wan spends 20 years waiting for a chance to train Luke instead of training another Jedi offspring, or having kids of his own and training them, etc. etc.
