The popular ones that come to mind (unpopular opinions):
-Hyperion by Dan Simmons. Tried twice and couldn't even finish it.
-Pandora's Star by Peter F. Hamilton. Tried reading it twice and audiobook twice, give up each time.
-The Long Way to a Small, Angry Planet by Becky Chambers. Finished it but it didn't really like it.
-Fifth Season by N. K. Jemisin. Finished it but didn't really care about anything going on in the book.
Oh no, they took down pictures of Hunter Biden's penis!
