So even after 15 years of poking holes in The Phantom Menace, my stepson managed to catch one yesterday that I had never caught before!
Qui-Gon saves Jar Jar from Boss Nass specifically for the purpose of having Jar Jar be his navigator through the planet core (nnnggh). Then when they're in the underwater ship, there's an exchange where Jar Jar asks how they're going to get to the city when they don't know the way. Qui-Gon's response: "The Force will guide us."
???? Why did Qui-Gon bring Jar Jar as a navigator if Jar Jar didn't know the way? If he was intending to let the Force guide them all along, what was the point?
It's hilarious how awful this script is. None of the other characters ever fulfill the function that they're supposed to. Jar Jar isn't a navigator; C-3P0, the language expert, never translates any languages in this or any of the other prequels; R2-D2 is brought along on Tattooine supposedly to show the ship's schematics to the junk dealers, but then just wanders aimlessly around the shop while Qui-Gon does business with Watto; the Jedi Council says that they'll use every resource to find the Sith Lord but then send Qui-Gon and Obi-Wan out to do it themselves; etc., etc., etc.
Seriously, did no one even read the script? Certainly George didn't. He must have knocked this one out on one morning before lunchtime and never looked back.
