Query: Extremely loosely based on the book.

To be honest I had very low expectations of this film. It seems that I didn't learn my lesson with the Hollywood rendition of the Chronicles of Narnia. This movie was worst. The only thing they kept were the names of the characters. The actors they used were all wrong. For starters Percy was 12 years old, how could he drive a big truck? (something he never did in the book); Hades never appeared in camp Half-Blood; the pearls were given to Percy by a Nereid in Santa Monica, etc. They should have named the movie something totally different. The author should have not allow it. Please Hollywood respect books.
