Looking at it recently and realized the last people in the opening credits of Dallas and it's spinoff Knots Landing were daughter and mother on their shows.
Young girls have always gone for the soft, non threatening, pretty types: Beatles, David Cassidy, Justin Bieber. There's this funny term online called "twink death" when a male celebrity gets old and loses their youthful male beauty.
I think why Chevy broke out back then was he looked like a normal good looking leading man but would unexpectedly be goofy and say silly things with a straight face and that made it more funny. It's basically Ryan Reynolds whole thing now. As he got older though Chase's looks started to go and instead of this young guy being charmingly odd it was now this old man being confused and his shtick didn't work anymore.
I think you can tell that story but for one movie as an epilogue. That's what Lucas intended in his original handwritten outline for 12 movies. Fans though wanted and expected another trilogy.
Lucas' decision to make Darth Vader Luke's father(which was late in the TESB screenwriting process), while elevating the movie and the original trilogy as a whole would artistically doom the prequels. It would have been much easier for Lucas to write a story about a friendship of two good guys where one of then is killed by the other's student who was already evil(as Lucas had originally planned) then it is a to write a good guy who turns evil and betrays everyone he loves. Someone with far better skills as a dramatic writer could pull it off but not Lucas. Similarly the decision to kill the Emperor and have the Empire defeated in the third movie would negatively effect the sequels. Lucas originally planned to do that after another trilogy but the movies turned out to be so time consuming and expensive to make that he just wanted to finish the trilogy. Once you defeat the main villain and the good guys win the story is basically over. There's nowhere to go.
Seeing unhappy people now hating Jon's return in Twitter say he popularized the "both sides are the same" mentality that has ruined politics now and I'm like did they even watch TDS when Jon hosted? There was never an episode where the majority of Republicans was not shown to be almost cartoonishly evil in both motive and executing their agenda. They were clearly the worst of the 2 parties. If holding Democrats accountable for not living up to their voters standards and wanting them to be better is "whataboutism" then I'm on Jon's side.
