SW ST aren't just bad movies, it also created a very dull era
No interesting characters.
First Order-Awful copy of the Empire.
New Republic-simply gone.
The resistance is extremely bland as well
It made the entire era awful and nearly impossible to extend.
PT might have problems with the movies, but its era was great and there are so much to develop/explore.
THIS is why most of the series were based upon dark time or close to OT era, but still you can't change the big picture, maybe that's why they moved to High Republic era.
