Enjoyed the movie overall, great special effects, lots of action. My 5-year old, to whom I've read all the books, loved it. But, they made a number of major changes from the books. The characters were older and some of the themes were more mature than they needed to be. Also, they left out some major plot elements that are integral to the larger plot (e.g., Luke's relationship with Annabeth, the prophecy). I'm not sure how they're going to work around them if they do make sequels. But, fun overall.
