Star Wars fans are difficult to please. While the original films from the 70s and 80s are universally loved, the fans hate everything since then to a greater or lesser extent. Maybe there is a limit to how many times you can tell the story of space wizards and space nazis chasing a MacGuffin.
Even on its release, the prequel trilogy at the turn of this century had a generally negative response. It tells the story of the rise of Darth Vader and the fall of the Galactic Republic. While its depiction of space politics has been widely derided as boring and ham-fisted, some of its aspects are interesting in retrospect.
The old republic is portrayed as tired. It still appears to have the glory of the past, but it is riven with factional fighting and disputes. The old institutes appear to uphold the old traditions, but even they are a shadow of what they once were. Procedure takes the place of action even in crises; complacency and arrogance prevent them from noticing the reality of their decline.
Palpatine, one of the space nazis, exploits these weaknesses and divisions, enabling him to declare a Galactic Empire. A lightsabre fight between Palpatine and Yoda destroys the Senate, symbolically indicating the end of the republic and democracy.
They should have used chainsaws.
