A good movie, fairly true to the book (books are great by the way). While the story revolves around Percy, there are good female role models in the story too -- making it entertaining for both boys and girls. My son (11) says, "Throughout the movie, after every exciting part, there would be a moment of still action, then a sudden monster or something swoops down and attacks them, making the movie a real enjoyable action movie."
We thought this movie was funny. The Rock does a great job playing his role, and we enjoyed seeing Julie Andrews as the head tooth fairy. Billy Crystal and Ashley Judd were good too. It's a good family "feel good" movie.
