EDIT: I also think it is funny how Snoke starts going on this aside and Hux is thinking, “That’s great and all but I can’t stand here and listen to you monologue because the collapse of the planet has begun.”
I imagine that the monologue would be mostly to himself as Hux scampered off, but it is indeed silly. That’s also one of the reasons I moved the breakup of the planet to after the lightsaber fight; that sort of thing works in The Search for Spock because one of the combatants is a battle-obsessed Klingon, but nobody on Starkiller seems crazy enough to do anything other than try to get off it as soon as possible.
