I think Star Wars Episode 8 The Last Jedi has become a really hot topic recently due to the divided audience views on it.
I have a simple thought that if you try to create a new trilogy for Star Wars or even other franchise with different directors and writers on each movies, you need a complete plan on how the story goes and they need to be consistent.
The movie alone is a really great sc-fi film but it also changed a lot of things in the past 6 movies(or even 7) like characters, settings in just one movie with all those sudden introduction and twists and it seems that it has failed to do the job to make audiences to accept them. I never thought those can't be changed but all of it just need good explanation and presentation. But with Disney on how they handle the planning of the new trilogy(I am sure those directors and writers have communicated with each other but they do lack of a direction that they should go. You can tell by watching some of the interviews of those directors and it seems each of them are only doing their own thing), they failed to make quite a lot of people to accept the changes.
