well everyone does it.....but i think if you are going to watch the movie DON'T read the book...
you'll be realy let down
like i loved the book Percy Jackson....the movie was ok but it was like thay opened the book read 1 page and baced the movie off what thay read.
the whole movie is on them findeing the perals but in the book the perals are givin to Percy by his dad.

anyway i think thay need to do better if thay keep making movies out of books.......u?
