Finished last night. I enjoyed it despite the premise of a train ark endlessly circling the globe. Season 2 likely next summer, according to the wiki entry production was mostly complete before the shutdowns.
I didn't see that a 3rd Season was approved already ... that means that they must like Season 2 pretty well.Season 2 starts next Monday.
And renewed for season 3: Snowpiercer Renewed for Season 3 at TNT, Ahead of Season 2 Premiere
