The best thing in "Percy Jackson: Sea of Monsters" is easily the action. It's a lot of fun to see monsters from Greek mythology terrorizing our heroes in modern settings. You see a mechanical bull destroy the demigod camp, a massive sea creature devour ships, an attacking giant Cyclops, and more. It was the highlight of the first film and it remains the highlight of the sequel. Combine that action with some pretty good 3D and you have a mildly entertaining popcorn flick.
The cameos are another highlight of the latest Percy Jackson film. Nathan Fillion appears as Hermes and provides some much needed comic relief. He throws yet another modern twist on Greek mythology by playing a UPS executive (Get it? He's the messenger of the gods.) Stanley Tucci also has a small role as Mr. D, or the god Dionysus, the god of wine. He's one of the headmasters of the demigod school and has some fun interaction with Percy and the crew while he rocks yet another impressive wig. Tucci does look a tad like Ron Jeremy which is unsettling, but I think that’s what he was going for.
I took my two young sons to this film. Only the older one had read the books, but both were quite happy with the movie. I must admit that I was looking for something more substantial, but if I was going to have to sit through a movie geared for kids, this at least kept me somewhat engaged.
While "Percy Jackson: Sea of Monsters" does have some highlights, it is ultimately quite bland. Percy is kind of dull as a character
