Dune

This book made me FURIOUS. It has no right to only get kind of interesting in the last 25% and exciting in the final <10% while being SO LONG.

World building and history ≠ handing your readers a glossary that requires multiple internal references to parse. If it's important to know to understand the story, make it the story.

Interminable, stilted dialogue that goes for tens of pages and action scenes that pass in a paragraph.

Form and execution notwithstanding, this book is also wildly bigoted, racist, and homophobic.

Also: we are in space, why do I have to read a book about a white boy named PAUL.
