Seen two episodes now...can't say I exactly see the analogy. Skins lacks the verisimilitude of Show Me Love. Its characters are exaggerations and its plots are melodrama. Which isn't to say Skins isn't entertaining.
As usual, I see the aesthetic similarities first, and I think both Skins and Show Me Love have the same charm of shows like Freaks and Geeks and My So-Called Life, actual teens playing teens, relative unknowns who aren't groomed within an inch of their lives. I think sex scenes in all of these works are particularly great--they have exactly the right balance of fumbling and fervent, rings pretty true to me. Skins is absolutely melodramatic but totally entertaining to me, (at least for the first series, the second and third have no redeeming qualities whatsoever), nostalgia might be at play here too, I spent most of my teen years in Europe.
