Percy's not supposed to know he's a kid of Poseidon until AFTER he meets Annabeth, until AFTER capture-the-flag, until AFTER Clarisse beats him up (which DOESN'T HAPPEN), gets knocked into water (NOT DRAGS HIMSELF INTO IT) and heals. THAT'S WHEN HE'S CLAIMED
Luckily, I was told that Rick Riordan is gonna help make a show about it, and it's supposed to be a million times better which is good, because my vocal cords cannot take much longer of this crud
Compared to the books? Yes they are bad. Movies alone? Idk how to answer since I already read the books and my opinion is formed around the books but if I didn't read the books, I might like them.
