Not a political piece by all means and still enough to throw in a panic fit the official italian storiography about italian unification. The background that many might think is exagerrated for cinematic reasons is actually a edulcorated version of how things went down. I strongly suggest anyone that wanna go deeper to read Pino Aprile - Terroni. All That Has Been Done to Ensure that the Italians of the South Became "Southerners" that is available translated in english on amazon. You'll find out that the first concentration camp on european soil werent the nazi but northern italian deporting sicilians. That overall the ethnic cleansing of southern italy obliterated between 500k and 1M people, genocide numbers. That that kingdom of two sicilies had a public debt of one tenth of piedmont kingdom, their monetary system gold backed. Their gold reserves about 10 times those of all the other italian states combined, neaples had the first opera house, the first university and the fist railroad and the industrial infrastructures was on pair and some cases superior to the north. It'll tell how cosa nostra was appointed at police officials by the king and how southerner male suspected of not loving the king with enough vigour were vanished in the north disolved in vat of acid.
It's a giant black hole in italian history that I, as a sicilian only learned in my thirties after being brainwashed as any italian kid into garibaldi and the red shirt and all that fan finction since first grade. So even a decent and entertaining work of fiction (with some solid anchor on characters that really existed) will do in order to question the official historiography and steer some curiosity in many who claim italian ancestry across the globe but arent aware why their ancestor mass migrated at once when prior to 1865 not a single sicilian had left the island.
