Hey, would you look at that? I've been slightly interested in this flick because of its roots in mythology, which I've always been into since I was in Elementary. There like super-hero stories, except that a lot of the heroes are incestuous jerks, and prone to being insanely petty.
Percy Jackson and the Lightning Thief wasn't a bad movie. It had some decent acting (except Uma Thurman could have definitely throttled back a bit), and the action was well done. The story had some holes you could toss a hydra through, but what do you expect from a kids' series of books converted into a movie? It ain't Harry Potter, no matter how bad it wanted to be. (It even got Chris Columbus, the director of the first two Potter movies). This is a popcorn flick, and if you have a kid with you, it would be even that much more fun. Percy Jackson even does a decent job of introducing Greek Mythology, even touching upon serious subjects that would have been avoided in other versions. And the actors they had come on to do cameos were really good. The guy they get to play Hades is also one of my favorite actors, so that was cool.
Also, Rosario Dawson is ridiculously hot.
So... check out this movie if you want. It won't blow you away, and it ain't no God of War, but its enjoyable.
