I've read the books and seen the movies, including this one. Greed is the top motivator for Hollywood, obviously. There's no other reason to split the third book into two parts. Then they had to pad out the action to fill the time requirements, which explains why this one was dulled to the point of putting people to sleep. Keep it, and watch it when you have insomnia. It'll be better than warm milk.
Despite that, I like Jennifer Whatsername work. Her best role was Winter's Bone, her first movie. Great acting in a really gritty world of meth and poverty. Oh, yeah -- Jennifer LAWRENCE? At least in this film, Woody Harrelson didn't chew the scenery as much. In the first two movies, he was as bad as Al Pacino in some of his work.
