Here goes:
Movie poster as new book cover.

Let's discuss this for a moment. Years ago I bought the book Four Feathers. After reading reviews, I headed to Barnes and Noble, only to find a shiny cover with Heath Ledger, Wes Bentley and Kate Hudson starting back at me. Now, I'll admit I thought they were cuties and she was also a looker, but I wasn't necessarily all jazz hands when I found that it was the only copy available. I bought it and ended up enjoying it (the movie too), but can't say I want to display it will all my other beauties.
Yes, a book shouldn't be judged by a cover, but I feel that this doesn't apply because the book is essentially being reprinted because the MOVIE has suddenly REINVENTED the novel. Look at these cool people endorsing this book that some weren't aware was even a book until A-LIST PLAYER was added to the cover. That probably means a lot of people are judging this thing by the cover. I don't like it. Not one bit.
Classic novel introductions that give away the entire story.
I may be in the minority on not knowing what every classic novel is about, so I apologize if this is a big, fat borefest. Thank you, Barnes and Noble Classics, for telling me exactly what occurs in The Woman in White before I've actually read The Woman in White (I finished it last year). Actually, I was smart enough to STOP reading once I realized I was heading into spoiler territory, and fast. Perhaps it's a no-brainer that the introduction contains the entire plot in 10 pages, but I was unaware and have suffered (fist shaking). I get that you want to introduce the reader to the work, break them in, bring them up to speed, but please explain to me why the entire storyline is divulged in those first pages?! I just don't get it.
Movie adaptations that rip the heart out of your favorite novel.
A couple of years ago I heard that there were talks of adapting Nicole Krauss's The History of Love for the screen. Let's just say I was not happy about it. Ok, so I know some people would be overjoyed. And sometimes I'll admit that I am. But for the most part I really don't enjoy books as movies. Books like The History of Love would never translate well. It just wouldn't. This might be a case of bias because of it's one of my favorite books, but really, those who have read it agree. When I discussed Extremely Loud and Incredibly Close (another example of beautiful literature) with those that had the expectations of something that wouldn't shame the book, several expressed that many of the best parts of the book were cut. It just couldn't be done in a Hollywood film. I refused to see it because I loved the book and couldn't think about all those beautiful moments left in the cold. And while I did note that the latest rage, The Hunger Games, was not so different from the novel, I can't say I'm entirely convinced it's a good idea. I get it's an adaptation, but that doesn't mean sacrificing the most moving/essential bits to make a sale.
Thoughts?
