What is the worst book-to-movie adaptation in your opinion?

'The Outsiders' isn't really a bad movie, but it doesn't live up to the wonderful book at all.

Chronicles of Narnia was atrocious. ._.

The 1st Percy Jackson movie. So many things and characters were missing.
Looks like they are redeeming themselves in the 2nd one though.

Either eragon of The Tale of Despereaux .__.

Fucking Twilight, good as a book, then the movie ruined everything, I can't read twilight without imagining the lifeless zombie Kristen and the constipated face of Edward.

Gene Wilder's Willy Wonka and the chocolate Factory

It was no where near the book and Roald Dahl himself said he hated it. Tim Burton's version was closer to the book.

The Twilight Saga. I admit I was obsessed with the books when I first read them. Then the filmes came out and that obsession with the books kind of just went away. The filmes were just awful. Maybe if they had a different cast, the filmes then would have been better. Who knows.

That Percy Jackson movie that came out in 2010 and The Hunger Games. I'd read all the THG books before seeing the movie and I expected it to be as epic as the first book was. It wasn't.
I really like the series and hope the 2nd film will be better.

Eragon, the book is awesome but I just didn't like the movie. And I'm not a huge fã of the Twilight filmes either, the books are okay, but the filmes were not. I thought the soundtracks were great though.

Percy Jackson and the Olympians was a horrendous book-to-movie adaption. >_>

ALL of them. Every single fucking one. Book-to-movie adaptations are horrible.
Although if I had to pick one it would be Eragon, they fucked that one up pretty bad -.-

Percy Jackson and the Olympians: The Lightning Thief. Without a doubt. That movie annoyed me so badly. They got everything wrong.
