I have like twice. I didn't enjoy it at all. It's a pretty bad directing choice imo. That said, if Denis Villeneuve can't do it justice then it might just not be possible to adapt the story for the screen. After his last two movies, he is arguably the best sci-fi director ever, and both Arrival and 2049 are entertaining while also being thoughtful and philosophical, which Dune needs to manage in order to be faithful to the novel.
On paper, his tackling this film is a dream come true for fans of the books.
