I read all the books, so naturally I was detail-picky. I was upset with the casting choice of Annabeth Chase, but did see that Alexandra Daddario is an amazing actress. I saw that they removed many key things, such as the fight Percy has with Ares, as well as adding things such as the need to have the pearls. But the movie was, on a scale from one to ten, a six on its compatability to the books. The special effects were amazing, and the actors were excellent choices. I cannot wait for the next installment of the series.
