For some reason I added the movie The Lightning Thief to my Netflix. This was a mistake. I was talking with a child actor at work who told me the movie wasn't true to the book. He said it was Annabeth's hair color. In the book she is blonde in the movie brunette.
After watching the film it is so much more than that. I came to the conclusion that this film is a poor adaptation of the book. There are scenes in the film that never happen in book. Characters/plot points are left out of the film. Then there is the fact that the kids in the film are like 16 or 17 while the kids in the first book are 12.
I talked with the kid actor at work who admitted that the first time he watched the movie he walked out. I think this is probably a true reaction. Kids are tough customers. If they read a book and then go see a film based on that book I think they expect that it will follow the same action of the book.
I'm going to finish reading the Percy Jackson series but I recommend that if people like these books they avoid the movie version.
