Take a gander at the trailer here and continue below to read more of my thoughts.
Now after watching that, doesn't that give you the "Wild West" look and feel just with a bit of high tech and space? Then you have the fact that the story is based around a group of scavengers who "Never back down from a job." I could have sworn I've heard that a billion times in the show as well. Quite a few great similarities if you ask me. I also find this as a huge selling point to my wallet.
Granted, there were neither real crazy powers as shown nor lasers to that degree, but I do like to find little things and build off them. We'll see how everything plays out and if we are one step closer to getting Firefly back. Just a little pipe dream of mine.
