i have quite a few things to say about this horrible movie (comparing it to the book)
1. appearances, percy is meant to have messy black hair and green eyes, same as poseidon, annabeth is meant to have blonde hair and grey eyes, grover is white with brown curly hair
2. personalities, grover is meant to be shy and loveable but in the movie he is loud and obnoxious, annabeth is meant to be confident but doesnt do much in the movie and is useless in battles
3. they are meant to be 11-12 not 16, it ruins the entire great prophecy aka the entire storyline for the books
4. camp half blood is way to crowded with everybody just randomly fighting when there is also meant to be volleyball and other activities other than just battle training. also the entire look of camp half blood is off, like where are the orange t-shirts, why is everything wooden, where is the greek architecture. The main thing though is where are the cabins decorated according to the gods, people just seem to have their own tents.
5. percy is meant to bring grover to the camp unconsious then meet annabeth who helps him. also the arent even slightly dating in the first book and her first words to him are 'you drool in your sleep' not it being love at first sight and them flirting and her saying 'i have strong feelings for you'
6. Chiron is meant to be the only centaur at camp half-blood and his personality is way off
7. since when did poseidon build a place for percy at camp half-blood. also percy was meant to be determined as poseidons son during capture the flag not being told by Chiron
8.the events of capture the flag are all wrong, annabeth and percy are on the same team and percy is used as a distraction
9. and also what is that voice in percys head, is it his dad?
10. Why does Hades come to camp? also he isnt that mean
11. demigods cant use technology, and where is iris-messaging?
12. the entrance to the underworld is through a recording studio that isnt on the map, not the hollywood sign, like wouldn't people notice??
13. lots of characters missing, Mr D, clarisse, nancy bobofit, the oracle!!
14. lots of scenes also missing, fight with ares, bus explosion, bathroom fight and sooo many more
15. why the hell was persephone in the underworld????
16. Percy and Tyson are meant to fight the hydra in the next movie not this one.
17. why is there a fight between luke and percy on the empire state building and not the scene in the forest of camp with the scorpion
18. and finally the entire plot is just screwed up, in the book their main objective on the quest was to get the lightning bolt, in the movie it is to get three random pearls and save percys mom
anyways, there is more but im getting to mad and should stop, this movie is horrible, please dont watch, instead read the amazing books because this movie literally cuts out every good scene
