Agreed, it's utterly vile and can't understand the love for it.
My assumption is that it's a bit like when you see the homes of folk who've won the lottery, put Georgian pillars on their Council house and filled it with everything gold plated or leopard printed from the Argos catalogue. Or maybe I'm revealing my own fantasies here.
The Italians have a very long history of over the top historical decor to drawn their rich-fantasies on, from Roman Empire through the Venetian Empire and up to recent excesses with Berlusconi and bunga bunga. Gomorra is probably a bit tame by those standards.
Or maybe it's just an attempt to counterbalance the ugliness of the rest of their lives outside their front doors? I always need antidepressants after watching a series, and I'm not really in any hurry to watch this one. I want to, obviously, but I'll wait until there's something else on NowTV that I want to watch. Of course by then Gomorra will probably have gone. C'est la streaming vie... or whatever the equivalent Italian version of that would be. Que series, sera maybe.
Well, if it wasn't Spanish... how did I think that was Italian right up to the point where I just got a sneaky feeling and did a bit of fact checking? I blame it on Doris Day singing with an Italian-ish accent.
