I loved the original hunger games books and movies. I never read this prequel and just watched the movie. The movie reminded me of why I loved the series so much. It is a villian origin story and usually I don't like justifications being given for what can be considered evil.
This movie just felt perfectly poetic. The music and Lucy's singing was beautiful. It brought everything full circle by introducing Katniss plant, the poison, mockingjays, etc. (spoilers) Though the end is ambiguous I thought even that was perfect, the confusion created with the mockingjays and Snow giving up his last bit of humanity in that frenzied state.
