Unlike a lot of Star Wars fans, I didn't read any of the books or novels or EU stuff nor did I try to find out what would happen in episode III through other means. So seeing the movie for the first time was a pretty big surprise to me. There were many things in the movie that I was hoping to see happen differently as well as many things that I was hoping would get resolved, but didn't. The first thing that stuck out in my mind was the final battle of Obi Wan against Anakin. I was hoping to see that take place on Degobah. The reason why is I always thought there was more to that scene in "the cave" than what was let on in ESB and there would be a moment sometime either in ROTJ (before I saw ROTJ) or the prequels where they go back to that cave and show more relevance to why Luke had that premonition in there. Before episode III, I thought that cave was the location of Anakin and Obi Wan's duel and just beyond that point where Luke sees ghost Vader was a cavern of flowing lava where Anakin falls to his doom and gets burnt, needing the suit. But then I thought, why would Yoda go into exile there if Anakin had been there? The plot would have to be worked around for that to make sense. Luke sensed a disturbing presence there because he had a subconscious feeling that was where Darth Vader once was and he was linked to him in some way.
The second thing that happened unexpectedly to me is how Vader got the suit. I had theories, some didn't even involve being burnt at all. I thought maybe he loses all his hair and needs the suit due to radiation overexposure. Lucas seems to always like to have lightsaber battles over massive chasms above nuclear reactors. Maybe Anakin falls too close to a nuclear reactor? I actually kind of liked that idea better, because being burnt like that would have made him blind and deaf. I don't know if heavy radiation exposure damages your eyes and hearing?
The third thing is Padme's death. I don't think anybody here liked the idea of her "losing the will to live." Before episode III, I always thought Padme would die a few to several years later after she has the babies and is separated from Anakin. That was the logical idea because Leia remembers her and said she died when she was very young. I think we interpret that as being 4-6 years old. Not right at birth. I thought the jedi would separate Padme from Anakin/Darth Vader when he starts turning to the darkside. The jedi lie to her telling her he died, but Anakin/Darth Vader goes searching for her and finds her years later. When he finally sees her again Padme is shocked to see him in the monstrously Darth Vader suit and she dies of shock. I think that would have been a lot cooler and deep than what we saw on screen. In order to do that though they would have needed another movie almost since the star wars movies traditionally have not jump cut years later and I don't think time jumps are in the style of the movies. That is why I think more of the episode III plot could have been fit into episode II plot making more room for stuff like this in the third movie. And they easily could have moved episode II story material into episode I. While I don't think episode I is as bad of a movie as some people, the movie hardly accomplishes anything worth mentioning in the continuity of the overall story. Like what many people have said, you could have fit episode I's story into the opening crawl of episode II. Hell, episode II too.
I have more to say, but this is all I will post for now. I did briefly search this forum to see if anything was similar enough to this but couldn't find anything specific enough.
