To be honest, I'd like to see and learn more about the franchise because the movies, old and new, never really explain a whole lot about the whole lore and why things are how they are.
I think that's fine. Many films/shows suffer from too much explanation, even getting whole prequels dedicated to explaining things that were background lore.
Leaving things unexplained allows us to wonder, to imagine what might have happened.
Just like the book, which does mention many past events, but they rarely go into detail about them.
To me when it came to Dune though it always felt like I just jumped in the middle of an ongoing movie, which makes it a little hard to understand the plot and the various narratives within.
