If you read my thoughts on Catching Fire, you'll remember I said it was weakest of the three books. That's because so little of it was important to the overall story arch. It was still a good read. You'll also remember that I compared the series to The Matrix trilogy. The Hunger Games, like The Matrix, is the best of the three and works on its own. Catching Fire, like The Matrix Reloaded, is a great book but depends on Mockingjay for it's conclusion. Unfortunately, like The Matrix Revolutions, Mockingjay is necessary for those who read Catching Fire and is the worst of the three on every level. However, unlike The Matrix Revolutions, Mockingjay does tie up any loose ends left by Catching Fire and doesn't suck all of the life right out of you.
