The Phantom Menace:
1. Cutting out as much Gungans and Jar-Jar as we possibly could, seems like a great idea to me.
2. Midi Chlorians need to go completely, that whole scene with the blood test could probably be scrapped now that I think about it.
3. No poop jokes
4. No dumb podrace commentary
5. No more "Yippee!"
6. Cut a lot of the bad dialog between Anakin and Padme.
7. Make the space battle as painless as possible, maybe take off the auto pilot so he doesn't seem like complete luck? IDK
8. Make Sidious much less obvious, people who haven't seen the OT shouldn't be able to identify that it's Palpatine.
9. Make Yoda less hidious as a puppet? (We need better source material)
10. No dumb celebration at the end, end it with the Windu/Yoda talk?
11. Please don't touch the Maul fight! If anything edit it into one continuos fight?
Attack of the Clones:
1. Cut as much love dialog as possible, it's just to painful. That also goes for the romping scenes, Portman and Christensen were voted least believeable couple for a reason. It would be interesting to try to make it seem like Padme just fell for Anakin because she thought she was going to die, or because she was stressed out? Maybe try to make it seem like she never really was into him as much as he was into her?
2. Cut out the diner guy (I forgot his name), there is a nice deleted scene in there that is of the droids analyzing the darts that could go in there if needed.
3. Make the Sifo Dias plot either make sense or dissapear.
4. No bar scene with deathsticks.
5. Zam isn't a changling but only shifted at the end in effect of dart poison.
6. At the beginning Yoda no longer feels warmness in his heart for Padme or something ridiculous like that.
7. No padawan map scene, the kids while cute were not pivotal in any way.
8. Shorten the arena scene if possible, I thought most of it was cool, but it never really seemed like it was going to end.
9. No droid factory bit, they looked like idiots running around, again I think there is a deleted scene that could be inserted showing a meeting with Dooku.
10. Take out the whole speeder chase in the beginning or shorten it way down
11. I personally like the yoda fight and wouldn't want to see it taken out.
Revenge of the Sith:
1. I know that it cant really be changed, but what makes me hate this movie so much is the fact that Anakins fall is SO DAMN QUCIK I can't relate to it at all. He goes from Telling Obi-Wan he loves hims, and the next time he sees him he is trying to kill him? He was super good and then super bad? What? The only thing I could think about doing is to take the scene out where Obi and Anakin talk before Obi goes to Utapau, that way there may be more tension between the two? But his unreleastic fall always made this movie practicly unwatchable.
2. Cut some of the opening space battle (buzz droids?)
3. I did like R2's oil slick thing, we need some comic relief, maybe just make the super battle droids not talk?
4. Take out the balcony scene with Padme and her hair. It's painful to my brain.
5. Take out Lucas kid, if Ki-Adi-Mundi couldn't kill those clones why should a preteen?
6. Make it be just Mace that takes on Windu so we don't have to see the others die so pitifully. Now that I think about it, it would be AWESOME to have Mace go alone, frankly bad-ass in my opinion.
7. Take out some of Grievous's coughs if you can, he was a cool idea and he was jst so damn sick all the time.
8. Find some better way to do the birthing scene, as well as fixing up her death. Losing the will to live? I've lost the will to live sometimes but I always bounce back! Maybe Anakin crushed her Trachea or something clever like that.
That's all off the top of my head, hopefully they make sense to others. If I think of anymore I'll post them.
