I haven't watched the first season yet but I enjoyed watching the second one, Deadly Games. At first I was worried since it is based on true stories, the story would drag and expected a bunch of boring characters, but I ended up liking the show. The story has good pacing imo, and it doesn't move too quickly or slowly. The characters are interesting and well written and I liked some of them. And although the ending was not satisfying enough for me it was okay (considering it was inspired by real events there was not much room for further dramatizing).
