The more I think about Star Wars (the original, the new ones are not even worth thinking about), the more I get infuriated how ridiculous the plot was.
I will break the Star Wars story lunacy, Myers Briggs style:
Emperor - An INTJ political genius (went from Senator to Emperor. That's some Julius Ceasar shit right there).
Grand Moff Tarkin - A no-bullshit ENTJ military commander.
Darth Vader - An ISTJ lieutenant who got things done by choking the shit out of subordinates.
Bobba Fett - A seasoned assassin, ISTP sociopath, most feared in the galaxy, etc
Luke - Emo INFP farm boy, Jedi Academy drop out.
Obi Wan - An elderly INTP mental masturbator whose greatest display of power involved getting himself killed in front of his student.
Han Solo - An ESTP deadbeat (hey, pay your bills to Jabba, asshole!),
Leah - The most competent one of the other rejects, not that it's saying much; a frigid ESTJ Princess with a short fuse, with her leadership abilities severely handicapped by her lack of tact.
Now which team would you bet your money on?
But before you give the answer, also remember that the Empire was backed by a massive army, had all the resources and personnel at their disposal, while the Rebels had... Ewoks (i.e. teddy bears living in the Stone Age).
