Regarding the broadcast: I do think something that galvanizes the galaxy so that they’re more inclined to join the resistance would be helpful. The broadcast is probably as good as anything in that regard, given what’s available to work with. But the content of the message itself is so meaningless and vague that it doesn’t necessarily accomplish anything. There’s no reason any of the younger rebels would recognize his voice, and he doesn’t identify himself. But something more than Poe’s awkward “somehow Palpatine has returned” would intensify that scene at the base immeasurably. Is there any Palp dialogue that’s on the cutting room floor from editing other scenes in the film which could be used to either extend the message or replace its content?
