I bought this to rewatch and own the first season. Nowhere could I find if this particular set came with a Digital Copy (UltraViolet). I was so very pleased to open the package and find a Digital Copy (UltraViolet) redemption code. I started downloading immediately, and put the first disc in my machine, and let the journey begin. I convinced a friend to watch the first episode, and we ended up watching them all together. Good Purchase, Good Times.
As for the story, well: aliens, guns, interpersonal drama, intrigue, hope and sorrow, romance, and aliens. The aliens deserved another mention, there are different types of aliens, and you will see the different roles they each serve.
