HBO's wildly popular Game of Thrones came to an end after eight seasons with the airing of the series finale Sunday night. The surprise ending [no spoilers here; but spoilers here] that spelled out who filled the power vacuum in Westeros left fans split at the end of a controversial and rocky final season. Twitter blew up with criticism from fans. The show's stars posted tributes to the project. Sophie Turner, who started playing Sansa Stark when she was barely 13 years old, credited the experience with making her the person she is today. "At 23 I leave you behind, but I will never leave behind what you've taught me," she wrote on Instagram. "To the show and the incredible people who make it, thank you for giving me the best life and drama lessons I could have ever asked for."
