I would like to add two ideas, I don’t know if anyone already mentioned those ideas, so I’ll just explain them here, they are both about the final part of the 3rd movie.

I think Yoda fighting Palpatine was a great moment in the 3rd movie, and it should be preserved. I saw people suggesting it should be removed from the third movie, but I believe it makes Yoda look like a coward, just running away and leaving the Sith to rule the Galaxy.

I understand that the fact that he is unable to beat Palpatine makes Luke victory seems “too easy” in ROTJ, but with some clever editing it is possible to make it look like Yoda was winning the fight but Palpatine was saved by imperial troopers. I mean, in the last scene, when Yoda and Palpatine where exchanging lighting, only Palpatine would fall. Yoda would stand on his feet but in that moment, imperial troopers comes and shoot Yoda, that falls when trying to avoid being hit by the lasers.

I don’t think Padme’s labor should be seen. Besides giving away that Luke and Leia are brothers, if Padme Lives, it doesn’t give a good explanation to why Luke was separated from Padme and his sister. I think it would be enough if we see Natalie Portman scene in Ana Bolena with a baby girl in the end of the 3rd movie, without seeing her labor. That way someone who sees the prequels would think she only had one baby girl (preserving the secret of Luke being Darth Vader’s son) and avoiding giving a decent explanation to why Luke was separated from his mother.

Anyway, just my 2 cents.
