Read the books.... movie is good, but read books first.
Someone is going to make fun of me for this, but one other thing that has drawn my interest is something I heard last year. Guess who else likes the Hunger Games Trilogy and had read all the books at least once; I bring you Mitt Romney of the Michigan Mormons. If someone as hardworking and brainy as Mitt Romney thinks there is some merit to these stories, well I want to check that out for myself!
In my own experience that is inadvisable.
If I read a book and then see the movie it ruins the movie experience because I can not help critiquing the movie adaptation of the book. I pick out the changes the screen writer made in the plot or changes made to the development of the character.
If I read the book after seeing the movie I pick these things up but I still enjoy the book.
