I think I've said all I want to about the Hunger Games trilogy. Mockingjay was just like the other two, but this time, instead of ending with a cliffhanger, it just ended. Think about the end of Harry Potter, the summing up several years in the future, but badly. In Harry Potter, I think such an ending was a good choice and provided closure at the end of an absorbing series that many kids had grown up with. Sticking an ending like that on a series like the Hunger Games was kind of pointless and dumb. Just sayin'.
All three books were quick reads, and they were entertaining enough. Mockingjay is my least favorite because, by this point, the reader knows exactly what is going to happen. It's entirely predictable. Collins even includes another trip to the Hunger Games - of sorts. The format is exactly the same as the other two, and so is the style. I got bored pretty quickly, and I'm glad I've gotten these books out of my system. That said, I did enjoy them well enough.
