This discussion reminds me of this gem:
Even as you were building up this iconic villain, you knew the tragedy behind it.
He’s so overwhelming in that first film, but you get to the point where you say, “Wait a minute, if he’s so powerful, why doesn’t he run the universe?” He even gets pushed around by the governors! They know the Emperor is the final word, so what happens is the same thing that happens in any corporation: Everybody worries about the top man, they don’t worry about his goon. And by the time the Death Star is finished, it gives them the sense that they have a bigger, better suit than Darth Vader. In a standoff between the Death Star and Darth Vader, they have no question about who would win, and it’s not this mumbo-jumbo Sith guy. So it’s even more tragic, because he’s not even an all-powerful bad guy, he’s kind of a flunky.
