We're only a year removed from AMC cancelling their original series "The Killing" after it finished it's second season.  It was brought back for a third season which was well received amongst critics and fans. However, Season 3's finale viewership numbers were too similar to the low rating numbers of season two's finale, and the decision was made to cancel the series yet again.

“We have made the difficult decision not to move forward with a fourth season of The Killing,” AMC said in a statement to Deadline. “We want to thank our great partners at Fox Television Studios, creator Veena Sud, an extraordinary cast and the dedicated fans who watched.” Fox TV Studios again is expected to explore other options for the series, but another miracle resurrection appears unlikely. The Killing, based on the Danish series Forbrydelsen, was developed for U.S. television by Sud, who returned for the show’s third season, along with stars Mireille Enos and Joel Kinnaman. “Fox Television Studios is extremely proud of all three seasons of The Killing,” the studio said. “We’re especially gratified to have orchestrated a unique deal with AMC for Season 3 that included a bold partnership with Netflix. While we would have loved to produce a fourth season for AMC, FTVS is immensely grateful to everyone involved with this moving series: our brilliant cast, led by Mireille Enos, Joel Kinnaman and Season 3’s Peter Sarsgaard; our stellar executive producer, Veena Sud; a remarkable writing and producing team; and a tireless, dedicated crew. Most of all, FTVS thanks the terrific fans of The Killing, who communicated their appreciation for the show throughout its run.”
