AMC continues their commitment-high track record as they’ve renewed this year’s freshman series Hell on Wheels. The cable network has now picked up 5 of their 6 original scripted series for further seasons, with Rubicon being the outlier. The post-Civil War-set show debuted to a strong 4.4 million viewers, and has aired seven out of the season’s 10 episodes so far. Deadline first reported the pick-up, and notes that while the series’ ratings have subsequently dropped, it still pulls in around 2 million per episode. I wasn’t particularly taken with the pilot and didn’t have the drive to stick around, but it appears the show definitely has an audience. The Walking Dead returns for the final six episodes of its second season in February, followed by the premiere of the fifth season of Mad Men (FINALLY!) on March 16th.
