Common Sense Note
Parents need to know that Percy Jackson: Sea of Monsters is the sequel to Percy Jackson and the Olympians: The Lightning Thief -- both of which are based on Rick Riordan's best-selling fantasy book series. Riordan's action- and humor-packed tales are enormously popular with elementary-school readers, but, like its predecessor, this big-screen adaptation does include violence and peril-filled scenes (and a few presumed deaths) that could scare younger kids -- even if they're familiar with the story. Unlike the first movie, there aren't any inappropriate references to sexy women or relationships. Ultimately, this is a hero's journey in which a main character and his friends save each other and defeat evil.
Some discussion of how the gods have children with humans and other creatures. Percy and Annabeth share some lingering looks and are protective of each other but aren't outright romantic.
Lots of fantasy action. A flashback shows a young girl being killed by a cyclops and then turned into the roots of a magical tree. A giant Colchis Bull wreaks havoc on Camp Half Blood, where it injures several kids before fighting directly with both Percy and Tyson. There are three big fight scenes between Percy and his friends and the bad guys. Polyphemus, a huge cyclops, keeps threatening to eat either satyrs or half bloods and fights with Percy, Annabeth, Grover, and Tyson. When brought back to life, Kronos is a frightening sight. Two characters are presumed dead -- and one does temporarily die before the golden fleece revives her.
A couple of "damn"s. A character almost says "bitch," but it comes out with a long "bbbbb" sound.
Percy's quest teaches that, in order to overcome obstacles, you need help, support, and guidance from friends, mentors, and people who know more than you. Percy must persevere despite his self doubt in order to protect his friends and his home. Tyson is a cyclops but not bloodthirsty like other cyclops; he makes it clear that you shouldn't judge someone before you get to know them.
Some of the characters wear Converse All-Stars. A UPS Store is shown during a pivotal scene, but it's actually an "OPS" (Olympian Parcel Service).
