I strongly disagree. I prefer things happening gradually and over time as it allows things to play out like an opera having them spaced out. It also allows Luke to go through the same journey as his father but make a different choice as they both learn the same lessons in their first two films but in the third film you get a different choice. It also has a bigger impact seeing Anakin as human longer instead of more machine than man. You don’t get that by having Anakin become Darth Vader in the suit right away. Same with the rise of the Empire. It doesn’t happen instantly but gradually to build the tension through subtle transformation.
