Looks pretty good and feels like a spiritual sequel to Snowpiercer (which I loved and I'm still pissed we might not get to see the final season).

You forgot to mention that Rashida Jones, Iain Glen, and Common are also in the show. They're just as strong selling points as Ferguson, Oyelowo, and Robbins.

Edit: Also of note: Graham Yost (Band of Brothers, The Pacific, Justified) is the showrunner!
