I'm reading Catching Fire now, and after watching the trailer and seeing what they have changed in the story, I'm still pumped for it. For me it's like Fullmetal Alchemist. I loved the original series, but when they remade it to follow the books I wasn't in the least bit upset. Two different series and I can enjoy them separately. HOPEFULLY that's how the movies go in relation to the books. Both enjoyable even if they are different.
I'm hoping they don't make this ridiculously over the top or extremely childish with that PG-13 rating, because as simplistic as the text is, it is still a great read at my ripe old age of 21.
