Like many, I went to see The Hunger Games this weekend with spousal unit and daughters. I liked it and would give it a B/B+. I thought they told the story well, it was paced well, and was faithful to the book. Some things got cut or changed, but any book-to-movie translation has that. I though the reaping part was especially done well and gut-wrenching.
My complaints (besides the jumpiness of the cameras) was that it did lose the grittiness of the book. In the book, the main characters were Appalachians who were half-starved living on squirrels and rabbits. But the actors in the movie seemed to be picked for their attractiveness and "hunk-iness" and anything but on the edge of starvation. And also that Katniss came to be a calculated killer but her movie character was much softer.
