"Zigzag" tells of a benchmark time in the life of the title character, a mentally "different" black 15 year old innercity boy (Jones). An ambiguous tale with an underdeveloped centerpiece which is hard to get your head around, this gritty film is fraught with character exaggerations so extreme as to make for poor credibility. Nonetheless, for those who can make the huge leap of faith required to buy into this drama, there is a touching story of the best and the worst of humanity in counterpoise with a somewhat poetic narrative. "Zigzag" is a misfire which seems to have a clear purpose with a flawed execution. C+
