This is where I think Disney could gain back some ground with disappointed fans by going full-on with the Lando series. It’s possible I’m way off here, but with the divided fan base and critical reaction to the Fett series, now might be a good time to step away from The Saga.
Calrissian is a long beloved character in the franchise and there are all sorts of stories they could tell that didn’t have to weigh in on OT or PT. Give us some stories about all those years before we met him. There’s no end to what they could do. It would be familiar but also new and adventurous at the same time.
I want an adaption of Heir to The Empire. Why not? Bring what is certainly THE most beloved EU material to life. What would be the risk? Just say it is an alternate timeline. It worked okay for Star Trek it would seem.
