I love The Expanse and wish there were far more episodes. We just finished Season 4 after a long wait. I am very satisfied with the story line and love the characters. Especially Amos, not sure but he is like "Psycho G.I. Joe" in a good way. I want to see him get evolve and heal up from his past.
My only complaint (besides I liked Naomi's old hair do better) is that I can't understand a lot of what the "Belter's" are saying in their dialect. I think I miss about half of what they are saying. Maybe I will have to watch it again ;).
If you need some good SciFi in your life, check this show out!
