Sure you could do all that, but if you draw even more attention to that problem people will wonder even more why the Falcon couldn’t just hover down to land like it does any other time. The SFX shot would have to convey that the blast hit a repulsorlift, making the Falcon lose altitude in that shot before limping out of the hangar.
Poe’s line about the landing gear and the shot of Rey opening a wire panel are both so brief that they’re hard to register, so when you see the image of the crash landing you’re kinda like “what?” Literally anything that would show it visually take damage would work.
Not only that, but those shots aren’t even the focus of the scene; the focus is on Rey, so it’s even more distracting. I think RogueLeader has a good idea - just comp in an extra explosion effect as they’re firing. There are a lot of places it could be added:
- As they’re firing on the ship en masse
- In the closeup shot of the Falcon’s engines
- When Rey dives for the ramp
- When the Falcon peels away
Maybe it could even be a large-ish explosion effect, as if someone fired a rocket launcher at the ship?
Also, I just noticed - The troopers are firing at the ship, they all get pushed backward and fall over from the Falcon’s exhaust, and then when Poe says, “Finn, move fast!” more troopers are firing on the Falcon from off screen. But then the very next shot shows that they’re all still knocked down and no one is firing. I can’t imagine we’d be able to fix that, but it’s another fun little continuity error.
