Let’s not get ahead of ourselves. Yes, Palpatine bring back is a little lazy/fan-servicey, but him back won’t inherently make the story of TROS not “original” (an overrated concept to begin with). We don’t even know what him being back means or how he’ll factor in.
Yes. maybe we can save our soapbox speeches for after the actual movie is released.
But then maybe some of the exaggerated cynicism will no longer apply!
Though I guess that’s never stopped anyone before.
