That’s kind of what happens when you continue a story past the “end”. Life goes on, there’s a new war, more bad guys, Patton dies from a weird car accident. It’s the innate problem with epilogues.
the issue is... people fought and made sacrifices for a better tomorrow .. to defeat evil..
yes, life goes on. But where was the pay off for the original sacrifices? The emperor was killed... the assumption was the rebels WON... peace would be restored ... the sacrifices made, worth it..
But this series starts off as if the war was never won... peace was never restored... the good guys never got back in control, ect. It just picks up as if none of the conclusions from the previous series even happened. Then systematically kills off every one we love and replaces with them a bunch of people we really don’t care that much about.
They should have just jumped further into the future if they wanted to start with new actors. After a 100 years of peace or whatever... evil rises again or some such. Heck they could have even kept Luke alive that long, since yoda was 100’s of years old, due to the force.
