I have watched and been a fan of many sci-fi shows over decades, and I would say this might be the best realized. It's so much more then space, and science, and fiction. It's a story about us, and what it means to be human. The writing is superb and the characters are so well thought out. I will miss this show and sad it won't continue forever. If it did I would watch every episode. As a side-note, I hope writers and TV makers take note of how diversity was done on this show. It just happens. No fanfare, no comment, just people together staying true to their characters. It's exquisite.
