Mockingjay Part 1 of the Hunger Games trilogy opened big this weekend, raking in 123 million dollars. Its down a little from Catching Fire, but insanely strong regardless.
They are very good books and the movies hit the nail on the head so are well worth the watch. And I must say they do a good job explaining what is going on. Too often movies that were adapted from books are a bit confusing and don't really cover the plot well. The Hunger Games do.
I'd recommend book and movies. In either order. Cool stuff.
