The unglamourous reality of the workings of organised crime in Italy are revealed in this grim, thinly fictionalised story. There's no glamour here: just a form of business in which violence is an institutionalised part, a shadow state, in effect, only with a high rate of marginal taxation, a strong line on punishment, and no policy for the common welfare. The reality of how it feels to grow up in such an environment is plausibly conveyed. What we don't see, perhaps unsurprisingly, is too much sign of anyone showing heart; and in consequence, it's a bit hard to get into the story, and care for the mostly unsympathetic characters we meet. 'Gomorrah' isn't a great film; but it is a useful corrective against the myths of Hollywood, albeit one with a rather depressing view into one particular corner of the world.
