The world of Dune is so rich and thoughtful that it's a shame that Pt. 1 of the movie necessarily had to downplay a lot of the world-building for the sake of conveying the essential story.
More and more, I'm coming to prefer the merits of a TV series for long-form storytelling and recognizing the weaknesses of feature films (even for a two-parter like the Villneuve Dune).
I love this era of TV that we're in, which I feel is best exemplified by HBO's programming. It gives me hope that the upcoming Sisterhood of Dune series is being produced by HBO. Although it has seen some significant shake-ups during it's production so far, so we'll see.
That said, I already watched this trailer 3 times this morning and will be there as soon as I am humanly able. So stoked.
