You are wrong there Rob. There is totally spies that betray people. Bothans.
And they only exist and then were tortured and killed off camera.
That's what you get.
Bothans just spy, they don't betray people. Sneaking is totally okay, not immediately severing ties when you are on the opposite side? NOT okay.
No, don't think I have (or not without some payoff like making the people who can see you roll their eyes or laugh). Also, neither of these people had peculiar ways of speaking. Also...just in terms of screen readability it seems weird--why would you have two people mouthing the same words in a movie without a specific purpose? That seems unnecessarily confusing.
If screen readability was something in Lucas' brain, we wouldn't have had minutes upon minutes of CGI animals added in and distractingly moving in front and behind of shots in Mos Eisley. It's just as likely that Lucas saw someone do that in real life and thought to himself "that mouth thing is a thing that is funny. I will have Jar-Jar do it, because Jar-Jar is funny."
He's not a big fan of ambiguous character alignments. Need I remind you of his reasoning for having Greedo shoot first? His exact words: "Because I was thinking mythologically — should he be a cowboy, should he be John Wayne? And I said, ‘Yeah, he should be John Wayne.’ And when you’re John Wayne, you don’t shoot people [first] — you let them have the first shot. It’s a mythological reality that we hope our society pays attention to.” When you leave him to his own devices, you get a world where good guys are good guys, bad guys are bad guys and everyone just says how they feel all the time while sitting at a couch in shot/reverse shot.
I know there's a tendency in nerd culture, especially among the fans that get real obsessive about shit like Star Wars, to overanalyze every single thing, but Star Wars' strength is that it's really all there on the surface. It's not a world with secret hidden narratives, because that's not a level Lucas operates on. The Prequels are basically eight hours of Lucas' unchained id writ large and it's nothing but lasers and computer monsters and spaceships and a dash of racism. He didn't write these movies with anyone else, so they're entirely on his level of pew pew lasers and space mans. There's no Kasdan to save him and that's why there IS no deeper level to these films. They're written by the man who thought Darth Icky was a great name.
And Obi-Wan didn't murder Owen and Beru to get Luke to leave with him either.
