The Lightning Thief review: Violence- LOTS for a PG. Expect no shooting, but lots of swordplay and scary monsters. The minotaur scene wasn't as violent as I predicted, but the scene with Medusa was lengthy and definitely one of the scariest parts of the movie. If you have any mature 8 year olds or younger, that part will most likely scare them. A teacher changes into a Fury, and picks up Percy, which contains some scariness. Many monsters including one with like 7 heads and then it grows 2 more. Oh, I forgot to mention, in the Medusa scene, they end up cutting her head off and taking it with them. Yeah, so I think you get the point on the violence. Sex: Some flirting between Anabeth and Percy, and in the end they kiss. Peresphone sees Grover in the Underworld and shows obvious love for them. Grover makes some sexual remarks. All of this will go over kids head's though, so no need to worry; but the part in the casino is fairly explicit. Language: H**l, A**, g*d in a bad way, and D**M. Drinking - The biggest part is definetly in the Lotus Hotel and Casino. They eat these flowers which make them not want to leave and party all night. There is drinking in the casino, and it's obvious the kids gamble. A guy in there seemed to be addicted to the video game he was playing. Gabe (Percy's step dad) always asks for a beer and orders the mother around. Overall- I honestly think if you have read the book and you go with a friend who hasn't, the friend will love the movie and you will be disappointed. I went with 2 friends, one has read the book ,and one who hasn't. You can guess who liked it and who didn't enjoy it as much. I have read all the books, and I admit I was disappointed, but still, with an ABSOLUTELY AMAZING book, you have a pretty good movie. Let me say why this is true (about people liking it). In the movie, they left out Ares and his daughter, Clarisse. They have almost the most important parts in the movie! The actors miserably failed to capture Rick Riordan's astonishing characters.You see, one who hasn't read the book won't notice these problems, and without them, it's a great movie! If the movie was like the book, I would give it 9,999,999,999 out of 5 stars. Yes the book is that amazing and the special affects in the movie could have made it ABSOULETLY FANTASTICLY ASTONISHINGLY FABULOUS! Overall, you need to read the book first to understand it, but you can still enjoy it without reading. Can't wait for "The Sea of Monsters" to hit theaters in 2012! Age group- mature 7 year olds and up. (the reason I said this was in the theater, I saw a little girl probably 5, crying and constantly telling her dad she was scared.) I know this review was immensly long (my longest yet), but I really hope it helped you figure out if you and your family shall see "Percy Jackson and the Olympians: The Lightning Thief".
