I agree that the OT doesn’t need prequels nor sequels. Like me, you probably see SW from an artistic point of view, but Disney/LF want more, so here we go 😄
In any case, a solution for making better sequels was already found years ago: in a way, TESB was not a SW film (or at least not like the original SW), yet most of us love it. Why? Because it was well crafted, it was able to stay true to the original movie, while expanding it with new concepts: a perfect balance.
So it was possible. I just wish they’d kept trying going into that bold direction for the ST.
