I have never been to a midnight premiere or seen a movie twice, until I seen this movie. I'm writing this a little late, but better late than never. I read the Hunger Games and Catching Fire before seeing the movie and it captured all the big major parts of the book. It did take a different viewpoint than the book, which I thought was kind of cool too.
I know people who haven't read the book beforehand were confused with things, so I'd recommend reading the book before watching the movie to better understand it.
