Absolutely no substance. I went in looking for a gripping return to a younger, more war torn Panem, and I got a spineless young one-day-President Snow whelp without a morsel of substance or actual drive who is our guide to the post war Capitol. He doesn't go tipping over the edge - he doesn't start as a character worth vouching for only to turn to a darker side. I kept waiting for that which never came. You dislike him immediately, you lose patience with him before the 10th games even begin. We dont get a character torn by the war, we get an entitled brat with superficial beliefs around the capitol's superiority as the controller of panem and defender against supposed chaos. Every other character is thin and underfed like a district 12 street dog. No depth, just another plot device. with the exception of Dr. Gaul who was intriguing and yet not fully fleshed out. Coriolanus Snow is fickle, whiny and somehow believable as a manipulative puppeteer of his peers? his 'love story' with Lucy Gray is paper thin - makes no sense based on their "bonding" in the hunger games. And the references to Katniss and "may the odds be in your favour" made me cringe. The only part that strung a heartbeat of authenticity was the origin of the hanging song and the eery nature of the mockingjay.
Not a good tribute to the original trilogy's legacy in my book.
