Well, I read the book before I saw the Swedish movie and.. well, they left out so many, to me, important parts that made the whole story fit together like a symphony. They even took away main characters that had huge roles in the book. So, it was a great disappointment to me. Same with the book, and later movie, the kite runner. Book was amazing. Sad, funny, intriguing. Movie... meh.
But ofcourse, the movie would've been at least 4 hrs if they keep everything. But still...
