Fantastic end to the series, and I think it holds alot more power if you watch the series first.
City of God is one of my all time favorite pieces of cinema, so checking out the companion film was something I was interested in. Its by a different director, but kid of about the same sort of subject matter. Some of the same techniques, but not as gritty and powerful as City of God. Its more of a made fore TV type of favela film.
