This is the fifth and final time I've tried to read Dune and I've decided it is not for me. 
 For starters, there are way too many made-up words thrown at you all at once, so you have no real idea of what things look like, what they are, it's just lazy writing. I think made up words are good when used well, within context to give you an idea of a place and it's history, but when you have ten invented words on a page, all I end up is irritated. 
 Also the writing separate from the made-up words is really bad. Dialogue is stiff, and the author has found the perfect way to remove tension from a story which sounds like it has the makings of an interesting plot, with betrayal and attempted murder, by revealing who the traitor is before you even know there is a traitor. And giving the characters incredible intelligence abilities which they use slightly oddly (in the little that I read, anyway). 
 I don't know why this book is so highly rated or why I've had it recommended to me so many times. I obviously cannot see what everybody else does, but I think that's because I am not willing to look past bad writing. I don't care if there is great world-building - though I didn't get far enough along to be able to say whether I thought the world was great or not. It was fine so far, but nothing incredible - or if it's informed an entire genre. If it can't stand by itself without explanation by anybody else, if it reads as really dated, then it's not a good book.
