The only change I would insist on is this: re-instating the Fox Fanfare. Even if it’s just the music over a black screen, as long as the timing matches the other films. The movie felt a little naked without it.
I recently read descriptions of all the deleted scenes, and I don’t think any entire scenes need to be restored. What I would do is re-instate some brief shots that were cut (the Constable on Jakku for example). Basically anything that would give the movie just a little more breathing room, to slow down the pace just a tad.
Overall I loved the theatrical cut, and I don’t think it needs an overhaul.
Not sure if this has been posted in this thread before: http://www.slashfilm.com/star-wars-the-force-awkens-deleted-scenes/
But I think most of the cuts sound like they were good calls. A lot of the Leia ones were probably due to the acting involved, but the script sounds PT-like as well, if the novelization is anything to go by.
I’ll certainly be curious to see a lot of these edits if we get a chance (especially the weird ESB alternate angle idea. Damn that would’ve been controversial). But I don’t think I’ll end up wanting most of it included, aside from stuff that better sets up the state of the Resistance and gives some better impact to the destruction of NotCoruscant.
