I'm 3 episodes through Supersex.
Contrary to what some reviewers said I didn't find the pornography gratuitous yet. In fact I'd say the first episodes are like your typical Italian drama of a poor kid from a poor family in a small village without any prospect in I assume southern Italy going through his rites of passage and leaving home to escape being entrapped there like his family. (this has to be 1 in 3 Italian dramas I watch).
Some Google reviews said it was borderline pedophilia using child actors who spy on his brother and his brother's girlfriend having sex or looking at a porn magazine or having gypsy bullies pulling down your trousers and yanking at your dick. Wasn't that how most of us were raised? Anyway I'm sure the 21st century kids using their mobile to watch Pornhub is more damaging.
Borghi is only starting to feature in the show now (there are child and young teen/adult actors of him). I'm guessing they want to develop sympathy for him - lost family, lost brother, shattered illusions, his childhood crush turns out to be a prostitute but so far it's not working for me yet.
