The big problem with the third entry in the Hunger Games series is that it's part one. The third volume in Suzanne Collins' trilogy should never have been split into two films. Not only was this obviously done for the money (the series is all mega-blockbusters), but the result is a film that feels too long and is not very compelling. Not to mention that, on its own, Mockingjay - Part 1 seems to advocate a violent revolt against the corporate powers-that-be (i.e. nations like Canada and the U.S.). Having not read the books, I can only hope this will be corrected in Part 2.
I have written a long review for Canadian Mennonite and I will provide the link in a few weeks. In the meantime, Mockingjay - Part 1 gets only **+, the weakest entry in a relatively mediocre series. My mug is down.
