I don't believe you. The movie was amazing, you can't base an opinion like that on a short bit of it. You sure it wasn't some other book? It's been praised tones, so yeah - I don't know where you got badly written - but whatever, you're missing out on a fantastic series. I mean it, I'd say it has to be my favourite series right now.
Movie then. I watched part of it, got bored and turned it off. I read part of the book in a book store when I was considering buying it but it was so badly written it was making it too hard for me to actually enjoy the book.
