If anyone ever wanted to prove the point that sometimes the movie is nothing like the book, this would be that movie. It's a good romp through some Greek mythology, just like the novel but it's totally different. I would've liked to have seen Percy be a 12-year-old hero because kids don't get to see a lot of strong characters like that. However, Logan Lerman did a great job. It was fun.. definitely not for kids younger than 9 or 10.
I agree that this was a movie made for the fans of the saga. I wouldn't encourage anyone to drag a friend that hasn't read the books simply because they don't know the story and what's to come. As for the movie and actors, Lautner does overact in some moments. Kristen Stewart does act a little bit better in this one--not quite the same acting that she usually does. Pattinson's absence in the film is not as heartbreaking as in the novel. I barely cried unlike with the book. The sadness and desperation is hit upon but the action keeps you from falling into the abyss that is New Moon. I'd recommend seeing this movie to a friend but only if they are not a butt or one that has a bad attitude about the Twilight phenomenon.
