I have two. The Ritual and Drowning.
The Ritual is pure smut. 61 chapters and every one contains a graphic, demeaning sex scene. I’m convinced the author was an adult film screenwriter and decided to try their hand at writing a novel. There isn’t a single likable character in this book.
Drowning isn’t a great work of literature. I felt that the characters were very two-dimensional. I hated how naive the author made the protagonist. It made me have a lack of sympathy for her. The ending was series finale of Dexter bad.
The Passage by Justin Cronin: a cool idea, for sure, but the author seemed so obsessed with the idea of writing the twenty-first century’s version of The Stand that he forgot to write…a good book. I was in a grudge match with this book by the end, especially after hundreds of pages of “oh children are so important, parenthood is divine” led to a passage (pun intended) told in flashback about the most exciting/terrifying part of the book.
Not just that, but he skipped an entire romance’s development by (again) having it told in flashback in someone’s journal, then saying “oh these pages are missing”.
It also didn’t have to be 800 pages long, ugh.
