What’s the issue with the “for just minutes” line?? I think it’s pretty straightforward:
The original plan is to disable the tower on the ground, when they reach Exegol Pride switches the signal to the command ship, so the plan changes to disable the tower on the ship, they succeed in disabling it, which leaves the ships stuck “for just minutes” (Poe reiterates this by saying “Nav signal’s down, but not for long!”), but Finn decides to take the whole ship down, which leaves the fleet stuck for good.
Of course there’s still the tower on the ground someone could fire back up, but at that point there’s a whole galaxy of ships attacking the Sith Fleet on their bright red weak point so it’s safe to say “they’re toast”. The whole fleet is destoryed, and the people who built it are crushed by rocks, so it’s all taken care of. The whole thing is kinda dumb, but if we removed all the dumb things in this movie we’d be left with nothing. In this case removing the line would turn the plan into a “we do this one thing and we win, period.” wich would massively lower the stakes of the Exegol assault. Instead the plan is to stall the ships from leaving Exegol long enough for Lando to rile up ‘the galaxy’ to come and take them down.
Disabling the navigation systems is not the main goal or the win condition, the plan was always to temporairly delay the Final Order. In fact their “victory” in disabling the tower happens during the ‘lowest point’ in the battle, since “no one is coming to help them”.
That doesn’t make sense though. You’re saying that the entire Sith Fleet is stuck for good because “Finn decides to take the whole [command] ship down.” When was it established that knocking out the command ship would cause a chain reaction and blow up the entire 10,000+ ship fleet? If knocking out the command ship will cripple the entire fleet, why do they even care about the nav tower? Why don’t they go after the command ship in the first place? It’s not like the nav tower is actually a shield generator that’s protecting the command ship, because they establish that “shields don’t work in Exegol’s atmosphere.” And how would that chain reaction work out logistically anyway? Is every ship connected directly to the command ship’s computer? And if so, what do they need the damn nav tower for??
The film makes it very clear that there’s only thing that unites the Sith Fleet - the nav tower signal. You take that out, the ships can’t leave the planet. The command ship isn’t even mentioned - not in the pre-mission briefing when they’re expositing all of this nonsense, not when they arrive on the planet - until it becomes the source of the navigation signal.
And if we ignore all of that and stick with the “command ship” theory anyway, that means we’re trying to do the entire battle sequence without setting up the plan, the goal, the plot, or the stakes. Hal, that’s not “subtlety”; that’s just sloppy writing. We can avoid all of this confusion if we just cut four words from the script. Four words!
