Amazing. Cinematically rich; compelling and complex. The anti-hero - a teenaged, petty criminal sentenced to serve time in a tough, adult prison, ruled by gangs. He has to grow-up and adapt to survive. He encounters a charismatic, protective, but ambivalent, individual, who teaches him to read and helps him to negotiate the prison. He murders him, by order of a gang boss, but it's a weirdly complicit killing, and in death, the mysterious, charismatic man becomes a dream-like, supernatural presence and a transfer of supernatural, prophetic power is effected by it. The young man has become A Prophet. Over time, he ascends the gang hierarchy, becoming the loyal, right-hand man to the boss, running the empire inside and outside the prison. He carries out high-risk, high-gain, audacious jobs; campaigns of ruthless violence and opportunity; acts of charity, benevolence, faith and piety. Ultimately, he becomes the powerful leader of the underworld empire. It is a measure of the film, that our sympathies are always with him, we are always rooting for him and ultimately, he is the hero.
