IKR! It's like they took a fan fic and decided they would be the plot instead of the actual book. The gave away spoilers too! THEY GAVE AWAY THE GREAT PROPHECY AND MESSED IT UP! They also revealed a bunch of people who were spies which you don't find out until ike 3 books later. There was no Beckendorf. AND Clarice was waaay too pretty.
Harry Potter is the entire series, and they /had/ to cut it down for timing reasons. Percy Jackson sort of fitted to the book's plot (but let's be honest they didn't really). The Hunger Games lost a few scenes from the book, but I just watched Catching Fire and there is one scene removed and one scene edited slightly from the book. So I chose Catching Fire.
percy jackson no way! the book is 100 times better and the movie doesn't even really fit the plot.
