Just finished watching Cyberbully on Channel 4, and I was quite impressed. Going in, I was expecting to see a show about the effects of cyberbullying. What I got was an intense drama about trolling and cyberbullying that was a hell of a lot better than I was expecting. Maisie Williams, of Game of Thrones fame, did an amazing job of carrying the show, and deserves major props for her performance.
If you're able to watch the show, I really recommend you see it.
