If it can be implied through editing or maybe changing a few mentions of her to different names, remove Maz and imply Poe sent them after the codebreaker. (Might be slightly incongruous when he asks if they got the codebreaker and doesn’t seem to know who it is.)
Get rid of Maz.
Get rid of ”Droids” style clowning around by BB8 on the casino world as well as using an AT-ST.
Bring the humor down just a notch through careful selection, avoiding jokes one’s mother would notice being gone when viewing again a year later. (Yeah… let’s go with that as a rough barometer.)
Possibly remove Yoda burning down a church and Rey having the Jedi texts later on. (No need for a surprise reveal; there’s already plenty of those and it was unnecessarily confusing to even me after two viewings! Rey can be safely assumed to go and refer to those texts sometime later.)
The last scene usually has no dialogue, but that’s not the case here. If one wanted to remove the Oliver Twist ending, the previous scene wouldn’t be any worse for it. (I probably wouldn’t do that though, myself.)
“Big-ass door”? I did not appreciate the degree to which the real-world/Marvelish/GOTG permeated language and quips. Removing just the handful of those that go over the top would be helpful.
Guys, I left TFA’s second viewing concluding that no fan edit was necessary, and only ended up doing one because a beautifully elegant idea emerged that was too good to leave unrealized. In the case of TLJ, I find myself wanting to grapple with this movie but finding not a lot to do. I’ll be following this thread diligently.
EDIT: Oh, and if we could remove maybe just one of the seventy-four death fake-outs, that’d be great.
