If he had been given more creative control, Lawrence Kasdan would have ruined RotJ. Kasdan is a better dialogue writer than Lucas, but ultimately, Lucas was always bound to understand his own story better, and he was right to stick to his guns on giving RotJ a happy ending rather than the darker one Kasdan wanted. (Kasdan always seemed to have a more grimdark, bleaker vision for Star Wars than Lucas did, and I think a lot of the choices made in TFA reflect that.)

Rogue One was probably better before the reshoots. The reshot ending was most likely conceived based on “rule of cool” and doesn’t really line up with ANH. I suspect the original ending was more consistent and thought out, only being changed at the last minute to make it “punchier.”

The sequel trilogy won’t age well. Partly because it lacks a distinct identity and tries too hard to be just a modernized version of the OT. Also, if the poor toy/merch sales for ST characters and content are any indication, it hasn’t captured the attention of a new generation to the same degree that the first two trilogies did (OT, PT, and Mando-themed toys are all selling great, by comparison). The ST started with a very strong first impression because of the novelty of seeing a more old-fashioned Star Wars movie again, but it will lack long-term staying power.

Also, I want to make an amendment to my earlier take about how Han should have died during the freezing process. Having thought about it, I realize now that would’ve been a mistake as well, since Luke and Leia would never have forgiven Lando if he had caused Han’s death. Taking part in rescuing Han was what redeemed Lando in the eyes of the other characters. So, basically, there wasn’t really any good window of opportunity to kill Han, and I’m glad he survived.
