Oh, no! You stated the obvious!
You didn’t need to watch the original trilogy to know that Senator Palpatine was a bad guy. Everything about him, from his face to his demeanor, screamed out “Future Sith Lord!” But for some reason, all of these clear indicators of his dark side went over the heads of the brightest people in the galaxy, including Obi-Wan.
It was infuriating to see the cast so clueless about what was obviously under their noses the entire time. It couldn’t have been clearer unless Palpatine scribbled a memo to the Jedi Council that he was the mastermind behind everything that went wrong in the galaxy.
