Dune books are great if you're more into the political landscape and how that affects the characters over action.

The 80s movie is great if you like shitty over ambitious directing with enough voice overs to last you a lifetime. Oh and Sting.

The new movies were more aligned with the story of the books not exact but more true to the stroy. Better than the David Lynch variant for sure. These movies and the 90s/2000s? Miniseries are the video adaptations that are not really Bad - imo

Eta: there's a George R. R. Martin quote about what inspired A Song of Ice and Fire - he is talking about Tolkien and the Hobbit/Lord of the Rings series... He mentioned how he was more interested in the politics after the war. Where did the orcs go etc... This is kinda the vein of Dune imo. The main character is Arrakhis IMHO. The stroy is one of politics.
