I personally think most of the issues people point to are fairly surface-level stuff that doesn’t really damage the movie as a whole. A second Death Star makes sense in-universe.
Return of the Jedi is a great movie, but I kind of think this is a stretch. The last one didn’t work, why would a second one with essentially no changes work this time? Palpatine gets a surprise attack on the Rebels I guess, but he still dies, they still lose the Sanctuary Moon, and the loss on Endor doomed the Empire.
