Quite an interesting movie - filmed in an almost 'cinema-verite' style. It is extremely authentic. The slums (or favelas of Rio), the dialogue, the gang members, the innocent by-standers are all depicted with a reality, that if it were not for the poverty, grimness and violence, would be considered refreshing. From that point of view it is much like 'City of God' but less nihilistic and the focus in this movie only centers on Rio de Janeiro. There is a positive out-look in that both the central characters are concerned with fatherhood; one is already a father and both do not know their real fathers (although this changes during the film). This creates a counter-balance to the slum and gang warfare. <br /><br />It took me awhile to understand or pick up on the storyline  one must pay close attention during the first 30-40 minutes to the characters and dialogue. I realized after, when I watched the DVD out-takes, that this was based on a TV series so that may be a reason for those difficulties.
