I’m old enough to remember it being cool to say ROTJ was bad because DS2 was a rehash. Also it was bad because Han Solo supposedly had poor characterization and should have died. And Ewoks were poor Wookiee cousins included for unfortunate humorous and juvenile appeal. Similar and more extensive objections made now are considered offensive. I don’t understand that.
All of those are valid complaints about ROTJ (well maybe other than Han not dying). But I still enjoy ROTJ, flawed though it may be in some ways.
TFA was somewhat rehashy but I still enjoyed it a lot.
TLJ? Eh, I don’t buy the rehash argument. But even if I did, I’d still enjoy it. See Awakens, The Force.
