I understand that with most book-to-film adaptations there is a slight deviation from the original author's work. You just can't fit everything that's in a book into a movie. This movie, however, is way off! My wife and I wondered if the screenwriter had even read the book. It's like he just took Riordan's characters and made up his own story, which was sub par by far. The story wasn't the only thing that was lacking. We weren't sure if it was the acting, the editing, the music, or a combination of them all, but it just didn't have what it takes to be a true blockbuster. We had high hopes for this movie. We were sorely disappointed.
