When A Book Is Made Into A Movie: Pet Peeves

So, we all love seeing our favorite books on the big screen, right? I know that as a child, some of the first movies that I remember watching are the Lord of the Rings trilogy (though it scared me at the time!) and the Harry Potter movies (the Fourth 1 also scared me!). It was after Harry Potter and the Deathly Hallows (the book) was released that I started reading the series, and I was about 11 years old. I remember that it took me a while to read them the first time around, but I loved them. I cried during the 6th book when Dumbledore died, and I cried during the 7th book. Luckily, I still had a while to go before the last of the movies were released, so my "Potter days" were long from over, as I'd only just been introduced to the fabulous world of Harry Potter.
Now, this is not a Harry Potter post. I love the movies and the books, and I was so sad when it ended, but Hogwarts will always be there to welcome me home. (That's a direct quote from J.K Rowling). This post is about movie pet peeves. Now, we all have them, especially when said movie is based on a book. If you're like me, you read the book before the movie comes out. So, you know what they leave out and what they add in and what they don't.

My biggest pet peeves are:

• When they make a really good book into a movie, and the movie is really cheesy and silly and all around bad. (For example, Beautiful Creatures. Yes, the cast, in my mind, was perfect. But it was the complete opposite of the book! I loved the book, but the movie kind of made it look bad.)
• Focusing too much on the romance. Okay, I'm a female. I do like romance. Do I want romance in every flipping scene? No. Do I want them to say "Oh, I love you," after they've known each other for only a few days? Absolutely not. Because that's not realistic. I hate the insta-love thing. I can handle it in a book, especially if it's well written, but I hate it on the big screen. It's just cheesy. 
• When things aren't properly explained. Alright, I've not seen too much of this, as book-made-movies are usually okay at trying to explain it, especially when not everyone's read the books, but I'd like to know the hows and the whys. Like, they could've explained the Horcruxes and Dumbledore and Ariana alot more in the movies, but they didn't. They could've shown a bit more of Neville's parents. They could've told us about Voldemort's mother. People who'd read the books knew that, but the non-readers didn't. They were probably confused. 

Now, I could go on and on. But it's getting late, and my eyes are starting to hurt from looking at my computer screen. So, I should be off to bed. Just a friendly reminder, The Fault in Our Stars will be in theatres June 6! So lets wear orange and bring along some Kleenex. :(
