WS - I hate missing stuff. Only had 2 WS left and a BIG stack of FS DVDs.
My wife went to sleep (no drinking binge or anything else to make her "pass out") during it too. I think the series either grabs you or it doesn't but the film definitely adds to the backstory. From the movie you would never understand Shepherd Book's (my favorite) or Inara's role or understand some of the other plots connected to tv series but it still stands alone.
You always pay taxes, one way or another, even if you live in Moose-butt, Alaska.
