No required readings or anything - books you chose to read ;)
I read the last book in the Eragon trilogy. I really disliked it throughout, but wanted the closure from the series. That didn't even turn out to be worth it really.
I found the opposite. I loved the books, and I've read them multiple times. It's movie I hate, oh god was it terrible
I bought every book, because a bunch of friends recommended the series to me. I could barely get past the first 100 pages of the first book because it was just too boring.
Some of the later books in the Sword of Truth series are really really bad. The author just uses them as a soapbox to espouse his hard core libertarian philosophy. I'm not really bothered by his politics, but the writing was just terrible. The main character pretty much stopped talking WITH the other characters in favor of talking AT them in multiple page lectures of how evil all the bad socialists/pacifists are. All of the bad guys were just evil caricatures of whatever he wanted to paint as bad.
Also, the author has a weird obsession with sexual violence. Every book (I believe literally every book in a main series) had some instance of sexual violence, including a multiple chapter bdsm torture sex slave relationship in the very first book.
I got through to the end of the series because I really didn't want to leave it unfinished, but I honestly would just rather have the hours of my life back.
I once read Battlefield Earth.
It was a glorious trainwreck of poor spelling, absurd scenarios that were constantly one-upped by even more absurd happenings, and overt, constant anti-psychologist propaganda. One literal caveman takes over an alien empire. All of it. Even the space parts. It's mind-blowing how contrived and out there the plot gets at times, it's wonderful.
As for a book I disliked, Twilight. I was recommended it by my girlfriend at the time. I hadn't heard of it prior, and this was about two years before the movie came out and its popularity exploded. Unlike Battlefield Earth, it was not so much a gracefully woven failure as it was a miserable piece of tattered cloth. I've yet to pick up its spiritual successor, 50 Shades of Grey, but according to the twitter debacle a few days ago, apparently Mrs. Meyer is a better writer than the author of the 50 Shades books. It is a worrying thought.
I made it to chapter 11 of Twilight before putting it down. I really made an earnest attempt, because everyone had talked it up so much. It was just too bland.
people are going to hate me but later (well the middle books i guess, i never read the final books) of the wheel of time series. what a load of tripe. I was gutted because i was reading on in hope that Perrin and Matt would get more airtime and the aes sedai might just get their shit together again.
All that repeating crap everytime any character met another character and filled them in on what happened "on screen" as it were just wore me down so much. Bloody Knitting circles can go hang. And then new spring came out and i threw it out a window. I've never rage-quit a series of books before.
And sadly Robin Hobb's first book ever in 1st person of the most whiney emo dude known to man. It wasn't bad writing just a wildly hateable character. Totally worth it to get to the Liveship books though. from worst to first!
When I was in French "Première" grade (equivalent to the US 11th grade), I was assigned to read the book "Désert" (basically Desert) by Jean-Marie Gustave Le Clézio, a French nobel-prize writer.
I haven't touched it since and at the time, the book was as dry as the title made it feel. A vast, empty desert, filled with uttered and boring words that sucked life out of each of my orifices. Those were hard times.
In recent memory, the Elemental series by Antony John. There was something about the romance and the problem with the main character that just made me hate the whole experience. Not only did I finish the book, but I read the second one that came out as well. And it was just as bad. Honorable mention to the Hunger Games series. Managed to survive the first book and couldn't get through the second.
Hunger Games is a good one. I thought the universe was super dope, but the narrative didn't really help it live up to its potential.
I mainly had a problem with the characters. They didn't feel very natural or realistic to me, but maybe I'm just picky.
I read Divergent. I usually like the popular young adult novels (sans Twilight), but I hated everyone in this book, especially the main character and her relationships. I wasn't a fan of any of the "twists," and even with the cliffhanger ending, I do not feel compelled in the slightest to read the other books in the series. Some people, like this book and that's just fine. I won't call it bad but it definitely was not for me. The only reason I finished it is because I bought it digitally on sale and didn't want to waste my money on a book I never read.
When it comes to immensely popular books, I make it a principle to read the book in its entirety before criticising it. This did not serve me well when it came to books such as Fifty Shades of Grey. However, giving this answer is like shooting fish in a barrel, so...
When I was in my early teens and a poor bookworm, I picked up Intrigues by Sharon Green. It was on sale and had a very pretty cover. However, and I feel like Grumpy Cat in saying this -- it was awful. Awkward speech, redundant exposition, bland characters with the exception of the villains, who were at least entertainingly bad. (Somebody since explained to me that this series, of which this book is one of many, being a bit like internet crackfic.) As a fond tea-drinker though, the fixation on it in the book was amusing. And the magic was pretty cool.
I bought the script to David Mamet's "Glengarry Glen Ross" thinking it would be awesome (solely based on the infamous YouTube clip) - it turns out that I just really didn't like the story or any of the characters. It feels like there's no development, but maybe I just missed it because I didn't like it. The worst part was the scene I linked to isn't even in the play.
What a bummer.
A book I actually finished was probably the bible, I guess. As a story it really jumps around a lot and is really heavy handed on some things. I don't usually have the paitience to finish books that I don't really like.
