All aboard. Snowpiercer has wrapped its four-season run by pulling into its final destination. When TNT unceremoniously dropped the series after Season 4 was filmed, AMC came in to ensure the series and the fans would receive the proper send-off. The ending brought things full circle, with the passengers once again fighting to take back their train. It brought a sense of closure for our main characters, with almost everyone getting their happy ending. But not every loose end was tied up, and there’s a chance we could see more of this frozen world someday.
