The Emperors return, no matter how it’s handled, nullifies Anakins sacrifice, Luke’s mission to redeem him & therefore entire point of the OT.
Seems like a bad idea.
How does it do any of that? Palpatine died, Anakin balanced the force, none of that changed in the slightest. The Empire still fell. Just because TROS created a tribe of Sith followers who brought Palpatine back to life does not change a single event or meaning of a single even in the OT.
