Dune is a classic scifi novel, which can mean it's anywhere between breathtaking genius and hardly accessible anymore. I found it a bit difficult to get into at first, similar to Ancillary Justice. Once I grew used to the storytelling device of an aggressively all-knowing narrator (frequently giving both/all inner views to all sides of a conversation), the world-building was fascinating, and despite the extensive narrator-explanations the reader is forced to make connections themself. My only misgiving was that large parts of the plot were too laid-out: the Mary-Sue protagonist, the evil antagonists, the good Fremen warriors etc. I hope that further parts in the series alleviate the clear-cut morals and abilities of the characters a bit. I'm looking forward to it – the world-building was exemplary. (Also, I can finally watch the movie now.)
