The Hunger Games books are in the same Young Adult fiction category as the Twilight novels by Stephenie Meyer and while I agree with Stephen King's assessment of The Hunger Games as being being more well written, it did seem the books from Collins followed a similar downward path as those from Meyer.
The later Twilight books often had a theme of overall weepiness and "can't live if living is without you" and in a similar fashion, the first Hunger Games book seemed the best and the second and especially third just had too many scenes where it hard to follow exactly what was going on. Fast paced can certainly be a good thing in writing, but just too many confusing spots particularly in Mockingjay as the third book.
I saw The Hunger Games movie first, enjoyed it quite a bit and then thought excellent the book it was based on. The second book Catching Fire still seemed fairly solid and then I just didn't care for Mockingjay very much.
