And why couldn’t someone use the Force to turn off the shield generator? Are the ship’s controls somehow Force-resistant?
There is a difference between a Jedi and someone who says “I don’t know how to turn off the shields, let’s use the force!”
Considering that Rey is able to use a Jedi mind trick without any training (at least that she is aware of), why would Finn not be able to use the Force to turn off the shield generator?
Because that’s not how the Force works
