I saw the Lightning Thief this weekend and it was a good movie, but It was hardly anything like the book. The storyline was still the same though.

Persephone was in it with Hades

Ares wasn't in there

Hermes wasn't in there either

Clarisse wasn't in the movie

Percy knew he was Poseidon's son BECAUSE his mom told him

gods weren't allowed contact at all with their children

Annabeth didn't have her invisible baseball cap!!!
