Given the very tough topic of social deprivation, extreme poverty and shockingly appalling living conditions, I expected "Cageman" to be very tough to watch. This turns out not to be the case. Instead, "Cageman" is a warm, positive and loving film about friendship. People in the caged housing live as harmonious as possible, supporting each other by their limited means.
