As a life-long science fiction fan, this series is probably the best sci-fi I've ever seen. I haven't read the books, but the characters and stories and world building of the TV series is exceptional. I'm so glad Amazon picked it up for production after the Syfy Channel was stupid enough to let it go. Season 4 had the characters spread out in separate story lines, but S.5 continues asking important moral and ethical questions while weaving the characters' stories back together and raising the stakes for everyone. The show deserves all of the praise it gets. And would someone please give Wes Chatham an Emmy already?!?
