OK, so, 1) The halos are unfortunate and I'm not sure whether or not they were originally there but the sad truth is that there isn't much I can do about them.
2) The burnmarks are something I'm not quite decided about, here's the thing: That shot has been reframed in the SE, so that you see more on the right and less on the left. Now I'm pretty sure this happened due to them going back to the original negative in order to get rid of those burnmarks and in the process redoing the shake, which was done in postproduction, so when I decided to revert it back to the original, I wanted to go all the way with it. You can't really compare it to cropping, because while these burnmarks were present on the print, the cropping was done by the projectionist and the print itself wasn't cropped. It's similar to the ripped frame in that tie explosion, sure, I could easily fix it but it was always there, it's even in the 97SE trailer.
3) The jaggies shouln't be there in the final version, don't know how they got there...
