To everyone else...RICK SOLD THE FILM RIGHTS TO THE LIGHTNING THIEF BEFORE THE FIRST BOOK WAS EVEN PUBLISHED... If you want a good adaptation... make one yourself. READ HIS SITE BEFORE YOU START COMPLAINING

and BTW, the Book is the most cannon but haven't you noticed that there is a section for Film for The Lightning Thief?
