I am watching Expance season 3 on Amazon Prime Video. It also states that Amazon Prime is now the home of the Expance series. This is the best science fiction series in recent years. As a Science Fiction zealot for over 50 years I have seen, listened, and read so much. One of the things I particularly like about this series is the completely believable technology. The interplanetary setting is nothing new but the interpretation, is again, completely believable. The luscious soundtrack by Clinton Shorter is a perfect foundation, the title theme “The Expance” is a anthem.
