If you don't, I'll tell you. Trollhunters is a Tv show, created by Netflix and Guillermo del Toro. It's about a boy who finds an amulet which makes him the 'Trollhunter'. The job of a Trollhunter is to defend the trolls from the evil trolls called Gumm-Gumms. I know it doesn't sound scary, but in troll speak it means: "Bringer of horrible, slow, painful and thoroughly calculated death". Threatening now isn't it? If you've never seen this show and you have Netflix, I suggest you check it out.
