Time Out review:
Although Babylon shows what it's like to be young, black and working class in Britain, the final product turns dramatised documentary into a breathless helter-skelter. Rather than force the social and political issues, Rosso lets them emerge and gather momentum through the everyday experience of his central character Blue (sensitively played by Forde). A series of increasingly provocative incidents finally polarise Blue and lead to uncompromising confrontation. Although the script runs out of steam by the end, the sharp use of location, the meticulous detailing of black culture, the uniformly excellent performances and stimulating soundtrack command attention.
Here (and above) is the trailer.
