Great acting from the cast; especially Jennifer Lawrence, the characters were as believable and entertaining as they were in previous films, this is pretty much the highlight of the film.
The plot however was dull and uneventful, as in nothing really went anywhere. in the majority of the film there was no tension; for the most part it was basically "stuff happens in a bunker for 2 hours: The Movie." which is super disappointing because although I haven't read the books; I'm told by people that have that they skipped a bunch of the action and downplayed the apparent love triangle.
If you wanted an action packed flick like the first two or you are the type of fan who doesn't like stuff in the book to be left out, you will be sorely disappointed as this is clearly a filler movie to get some extra $$$ before the series ends.
wait for DVD.
