The limited footage of the invasion doesn’t allow for a terribly flashy start (and is a little short for proper opening shots) but it’s more active and conveys more information more quickly. It is more of an ESB than ROTJ way of opening. I’ve considered whether new CGI shot(s) of the invasion could make for a stronger opening, not that I have the skills to do so, but also seems like a lot of work for relatively benefit.
I’ve added a new section in the OP, ‘changes editors would like to see’, to help aggregate things like this. This is the first item in the list.
