My review of this movie is pretty much an exact replica of Mockingjay - Part 1. Mockingjay is not as good as the first two books in the series and either part of the Mockingjay movies are not as good as the first two movies. It's because of how the story totally changes and its more about rebelling against the government than surviving the games. The best parts of this movie is when they are going through the action scenes that are reminiscent of the actual Hunger Games. That stuff was awesome and you really felt like you were a part of what was going on. The talking parts were nowhere near as good. Honestly - they were even painful at times. The weirdest thing about this movie is that for the grand finale in the series, it seemed like they didn't put as much money into the budget for it. It noticeably looked like a small studio film. Similar to the feel for the first film in the series. Catching Fire and Mockingjay - Part 1 had a visually bigger feel to it but this one kind of regressed. All that being said, it still is entertaining and watchable as you see how the story ends for all these characters you have been invested in for four movies now.
All of that being said - it doesn't matter what my thoughts of the movie are. Either you have seen the others and will see this or you have not seen them and you won't stop now. I enjoyed it but didn't have my expectations too high because I was not as big of a fan of this particular book either.
