I have a bad feeling about this.
It also takes it outside of its story - the fall and redemption of Anakin Skywalker.
Rather than go with Ep. 7 going way back in time to the original formation of The Republic with the Sith Wars, etc. would probably be more interesting without it having any effect on the main Star Wars story.
I just want them to get away from the clone wars time period. Do something either old republic or something between the original trilogy movies or after. Just anything but the stuff we’ve had for over a decade now.
