I found this movie intensely depressing. Maybe it's the constant relentless violence and shooting (no spoilers there - it's a mafia drama, what d'you expect, a bake off?). Maybe it's the total lack of hope for something better.
I understand a lot of Italian and have visited Naples, so 'get' a lot of the cultural references. The problem is, I found I didn't really care that much about the characters, who are pretty predictable: the mafia boss, the son, the wife, the underlings, the snitches etc. Nothing different from 1930s James Cagney movies except the Italian rap soundtrack! The instrumental music played is actually highly effective.
Also, so much of the scenes happen in near-darkness and the lighting seems to waver too, not sure why - but for that reason and more, I doubt I shall watch the other series of this.
For classic gangster mafia drama, I suppose The Sopranos will always be the standard.
3 stars.
