I had come across this series on Netflix, and after watching the first season, I love it! I thought it was a really awesome show from DreamWorks.
The series is about a teenager named Jim Lake Jr., who found an unusual amulet in the midst of a pile of rubble that was under the city bridge. In the evening, two trolls, Blinky and AAARRRGGHH!!!, came to Jim's house and explained that the amulet had chosen him to be the first ever human "Trollhunter," a guardian who protects an underground world of trolls and gnomes from wicked trolls. The troll pair also stated that the rubble pile belonged to the previous Trollhunter Kanjigar. Jim tries to adapt to his new-found position with Blinky and AAARRRGGHH!!! Also, with his best friend Toby's help, an evil plot is unfolding in the city of Arcadia, which makes it difficult to figure out who is a friend or a foe. That is all I know.
So overall, I love this series for its fantasy, humor, and awesome animation.
