"Has anyone actually ever managed to finish Moby Dick? Notoriously known as being one of the most boring books of our time, I guess it's fitting that I put this at #1."

"It's the Bible. Everyone, regardless of religion or personal beliefs, should probably read this. It can't be done in one sitting though. The brain tends to go numb."

"I finished it, and it's amazing but I can understand why people can't finish it. Victor Hugo is depressing, and he tends to ramble on and on about details no one really cares about. It's worth the effort, though."

"It's a short read so there really isn't much of an excuse to not be able to get through this, but if I had the choice I would have stopped reading it. Visceral, unnerving and disturbing."

"It took me three attempts before I was able to finally finish this one. While Tokien is remarkable, he can get wordy when it isn't necessary. Adverbs, adverbs, adverbs."

"If you're in the middle of reading this and you finally realize before finishing it that the author pretty much lied, that's reason enough to stop reading."

"Quite possibly the most poorly written and ill-conceived young adult fiction of our time. Yet, it's amazingly popular and that's why I tried to read it, but I couldn't once I realized the author only has a total of 6 words in her vocabulary."
