There are three types of people who will watch this show, but it will probably appeal to only two types...
Type one : you love space tv shows, they give you a possibility to see civilization in 500 years, you probably seen everything from Star Trek to LEXX and you are starving for a new space show...
Type two : you happen to be Cowboy Bebop fan by default...
Type three to whom this show might not appeal , people who were randomly looking what to watch in between their Breaking Bad /Brasic/ Peaky Blinders marathon...
