You see it be used against the sequel trilogy, especially The Force Awakens and The Rise of Skywalker. Even Palpatine’s return is criticized for “undoing the Chosen One accomplishment”… especially when these people are well-aware that Anakin only killed Palps specifically to save Luke.
What people don’t understand is that everything is temporary. What people think is that the victory of the OT only matters if it lasts forever.
The victory of the OT allowed for galactic peace for three decades. People were born and lived in peace because of the achievements of the OT. You need to come to terms with the temporarily of reality. Nothing ever lasts forever and thinking anything will… sets you up for sadness and anger.
Thoughts?
That may be how real life works, but Star Wars isn’t real life. It’s a fantasy setting. And Anakin killing the Emperor was meant by Lucas (at least retroactively) to be an act of cosmic significance. It was the destruction of the Sith and the restoration of balance to the Force.
Also, it wasn’t exactly 30 years of peace when the New Republic was embarrassingly corrupt and incompetent, and the new Jedi Order failed to get off the ground, and the main heroes of the OT all ended up failing at life and becoming estranged from on another.
That real-world cynicism has no place in Star Wars.
