The last Jedi could have been so much better had Han Solo lived until the Battle of Crait, faced off with his son, so that Leia, Rey and the rest of them could escape. (A special thanks goes out to Harrison Ford for that one). I believe he should have sacrificd himself at a better time than TFA. I would have done it in TLJ myself. He would have had screen time with Luke before his sacrifice.

Then Rey could have returned to Ach-To to finish any training she had left with Luke.

Had Carrie lived, she could have returned with Rey to see her brother in Episode IX.

Here’s my list

TESB
ANH
ROTJ
TFA
TLJ/R1 (tie)
ROTS
TPM
AOTC
