Go see the movie. You won't be disappointed even if you haven't seen the series Firefly. Serenity is well written and well acted which is what I expected from Joss Whedon and the cast. I laughed. I cried. I sweated in suspense. Whedon didn't pull any punches, but I was surprised at the deaths of a couple of major characters. I won't say any more because I don't want to create a spoiler even though the trailers on TV do it all the time.
