Tsotsi (2005)

Tsotsi (Presley Chweneyagae) is an opportunist gangster who lives in a Johannesburg slum. An impromptu nighttime carjacking is a doorway to great change for the thug, unearthing a streak of compassion that results in some truly believable human emotions played out onscreen, supported by flashbacks to hardship that give a deeper insight into his state of mind.
A woman named Miriam (Terry Pheto) adds a welcome sensitivity to the story, a point of contrast that is itself shaped by poverty and personal struggle.
The setting, the doleful but comforting voice of Vusi Mahlasela, the contextual skies, and the inner-struggles of not just the primaries but some of the more interesting secondary characters each make Dir. Gavin Hood's film an absolute joy to experience. If you've access to the alternate endings, give them a look because some are as good as what was ultimately chosen.
